Re: The Softimage mailing list

[Fabricio Chamon]

Hey Everyone!

I’ve been silently watching this list for a few years now. Just wanted to
say a big thank you for every single person that make it a great community!

This list helped me countless times, so I can’t appreciate it enough.
Really.

I kept on doing 3d (now in Houdini), but Soft has a special palce in my
heart =)

In the future I hope to meet some of you so in person, so we can have a
beer and discuss how great SI was at the time.

Cheers all.

Re: London work and how to pitch myself in these

[Fabricio Chamon]

Hey don’t want to hijack Laurence’s thread, but extending his questions,
I’m also interested in applying to some UK companies on the next months.

What are the chances of having a sponsored work permit these days? I mean,
of course it will depend on many factors like open positions,
recomendations, immigration policies and the artist skills itself.

I just wanted to have a glimpse of what to expect (or not), in a way that I
can prepare myself beforehand.

How inclined are recruiters to hire people from outside UK? How much of the
work force inside big companies (think Framestore/MPC/ILM/Dneg) are from
sponsored artists? What about medium size companies (think MvsM), do they
also benefit from/want/invest on foreign people?

I’ve also heard (from colleagues working in London) that houdini artists
are desperately needed everywhere. How much of this is true? Despite being
a generalist for the last 12yrs, I’m inclined towards pitching myself as a
houdini fx artist.. but I just don’t want to be too optimistic and hence
all the questions. Also this would help me puting together a proper reel.

Maybe someone had been through this process recently and can share some of
his experiences?

Thanks guys.

 Hi All
 After two gigs falling through in a row I'm a bit bereft of work, which
 leads me to think where do I pitch myself to companies now, who wants an
 old xsi generalist, who has been using/learning Houdini for a year or so,
 can light render etc in Maya, but thats the extent of my Maya?

 Feeling all a bit scrap heapy all of a sudden.
 Sorry for a pre weekend downer.

Doh, was there one week ago. Had a couple of beers with some fellow
friends.

Nice work on the crowds btw Pedro. It is interesting to watch how fast you
are climbing the houdini mountain.

I had a friend looking for xsi artists this week. Will check if he still
has an open position.

Re: OT'ish - Installing Crate for Maya?

[Fabricio Chamon]

I believe maya does support multiple uv sets in its current built in abc
implementation (at least from 2017 onwards). I have used it many times, the
thing is it is super picky about the file format and how it is constructed
(when coming from houdini in my case).

I had plenty of issues to transfer normal, multi uvs and velocity data. But
once you go through all the gotchas it works.

Re: The Maya Chronicles - or how retarded that software is...

[Fabricio Chamon]

Ok I have to agree with you Andy, I also had many crashes with SI.. no dcc
is 100% reliable, that is the nature of software. For me the big difference
is: I knew where to expect a crash in softmage.. like “move operators up
and down the stack=danger.. have a boolean going on? Danger times
1”..But in maya it happens out of the blue sometimes.. also the
hypershade have its own thing and hangs for good 5-10 seconds before
opening, even without shader thumbnails.

In the meantime houdini is working beautifully here, and handles the most
absurd node combinations I make when mistyping node names... only thing
that crashes houdini is the polydoctor sop

Re: The Maya Chronicles - or how retarded that software is...

[Fabricio Chamon]

Protip: have 2 maya sessions opened -> Begin working on one of them -> wait
for the crash -> kill on task manager -> fire up another session ->
continue work on already opened session while new one loads -> no wait 3
minutes for maya to start -> happyness (?)

This is how I work in maya EVERYTIME.

I’m lucky enough to be almost 100% houdini these days. =)

 It always been like that. I think my first responsibility in 3d world
 could be described as ''hypershade boy'' :), it was a Maya class where I
 had to start earlier, to launch Mayas and Hypershade windows, so other
 students would be able to use them before end of class (or something like
 that). More or less, that 'position' is possible today.



 Anyway I heard great news, there is a new principal developer in Maya
 team, who already have experiences all over industry. While we don't know
 for details of his actual engagement, here's what he did for Microsoft and
 Valve:

Re: Random Thoughts about H.

[Fabricio Chamon]

putting my little knowledge to action:

from what I understand about your question, you need to store your
calculated data as an attribute (per point, in this case). Then just refer
to it at other nodes on your tree. While at the object context there's no
such a thing as a generalized "get" node, because you'll be using the
attribute value directly inside nodes (at input parameters or inside vex on
the "...wrangle" nodes). Inside VOPs the equivalent to ICE "get data" is
the "bind" node and equivalent to "set data" node is "bind export" node.

Is that what you asked?

Re: houdini question (and where to ask)

[Fabricio Chamon]

thanks everyone. The ramp parameter kind of works but as you say, is not
that user friendly and does not show the points below 0. (that's ok, but I
wonder if it is possible to write a custom widget in houdini)

anyway, the thing I could not get right just yet is that sort of "get
maximum in set" thing. Sorry for using ICE language, I'm trying to be open
minded here, so please tell me if that`s not the correct mindset.

so on this graph:

[image: Imagem inline 1]

...how could I get the maximum value of the output noise node and compare
to a single point output of the same node?

>From what I can tell, I'd have to:

1- create this pointvop node with a turbnoise, then store the output noise
into an attribute (via bindexport?)
2- up one level -> drop an attrib promote (detail), set to maximum
3- drop another pointvop node with another noise node inside (same
parameters) and compare the result noise to that found on the atrib promote
node??

I'm 99% sure this is totally wrong...how would you go about that single
task specifically?

and finally, thanks for the suggestions on houdini forums and discord. will
try both (although I pretty much like this list =) )

Re: houdini question (and where to ask)

[Fabricio Chamon]

..sorry, hit send too soon.

Question #1: are there any equivalents to ICE "get ... in set"? or or do I
have to iterate and store values for later comparision? In other words:
what is the best or recommended workflow to compare single point data with
global point data?

Question #2: any nodes that resemble a fCurve node, like we have in ICE? if
not, what is the alternative?

and finally, I can see this list is becoming more and more houdini-esque
than ever..but, what is the best place to ask beginner questions like the
above? houdini foruns, houdini list, odForce...

Re: Find cluster from polygon - script

[Fabricio Chamon]

thanks guys. In the end I went for loops, and even created a handy function
that builds a dictionary with component ID -> cluster mappings. It is not
super fast, and it only supports 1 to 1 relationships, but served well for
its purpose. I just need one call, so I stored everything into an ice
operator that ultimately gets freezed.

here's the code snippet if anybody needs it:


function buildComponentClusterDictionary(inMesh, clsType){
//clsTypes: pnt | poly | edge ...
var clusters = inMesh.ActivePrimitive.Geometry.clusters
dClusters = new ActiveXObject("Scripting.Dictionary");
for (i=0;i<clusters.count;i++){
var cluster = clusters(i);
if (cluster.type == clsType){
var clsElements = cluster.Elements;
var aItems = clsElements.Array.toArray();
for (j=0;j<aItems.length;j++){
dClusters.add(aItems[j], cluster);
}
}
}
return dClusters;
}

////
//example//
////

//setup scene with sphere and a point cluster...
var sphere = CreatePrim("Sphere", "MeshSurface", null, null);;
SelectGeometryComponents(sphere+".pnt[1,5-8,12-15,19-22,26-29,33-36,40-43,47-50,54-LAST]");
CreateCluster(null);
ActivateObjectSelTool(null);
DeselectAll();

//call function and retrieve cluster of point #7
var clusterDictionary = buildComponentClusterDictionary(sphere, "pnt");
logmessage("Cluster for Point 7 is: " + clusterDictionary(7));

found the culprit... I was running this on a live alembic file...for some
reason it does not work. As soon as I freeze the mesh then it works great.

Setting ICE attribute DataArray in javascript

[Fabricio Chamon]

Hey,

lots of questions these days, sorry.

So I'm searching all day through the list and internet to find a solution
for this... I'm trying to set per polygon ice attribute values on a mesh
via sdk (javascript).
The subject was already discussed, Stephen Blair have some studies on it,
one solution was given but in the end I'm still not able to get it working.

So here's roughly my code:

var ICEAttr = highResGeo.AddICEAttribute("rbdId", siICENodeDataLong,
siICENodeStructureSingle, siICENodeContextComponent2D );
var myDataArray = new Array();
var faces = highResGeo.Facets;
for (i=0;i

Re: thickness - avoiding self intersections

[Fabricio Chamon]

yeah Johnatan me to, not super addicted to the voronoi stuff...that
straight edges are terrible... I like to use the iterative shatter in
IFX...to be honest IFX is a super tool for shattering, but it crashes often
with complex geometry (or skips the operator), which makes it unsuable
unfortunatelly. Houdini on the other hand is super robust, but needs more
advanced work to get that detailed edges.

I've already seen this guy's video, it is a nice technique, but it limits
you in a way you can't distort too much the geometry or it starts
degrading. In such a procedural oriented DCC like houdini I tend to dislike
having these limitations, because it makes you care too much about your
parameters, and your output is not 100% reliable all the time. One could
introduce small artifacts that are hard to see in dense meshes but will
surelly show up as holes or overlapping geo at rendertime.

anyway, I'm also diving slowly into houdini as projects allow, and I'm
liking it so much!

Hey guys,

is there a quick way to find which cluster(s) a polygon belongs to without
looping over all cluster elements?

Re: Houdini voronoi to Soft - disconnected faces?

[Fabricio Chamon]

@Cristobal and Andreas: yeah, that was it! thanks a lot!


@Morten: I'm a big fan of IFX, and currently using in the same project. I
love how powerful the ice operators can be to create nested shatters,
although it crashes sometimes. But I suddenly got this big messy mesh with
all sorts of bad geometry, so IFX unfortunatelly is not able to cope with
it (skips the operator), and I don't have the proper time to clean this up.
In the other hand, Houdini handles it effortlessly and that's just what I
need, so why not? =)

yes I tried converting to poly before the fuse node, nothing changed.

But as I'm now commited to the beforementioned workflow things are sort of
flowing.

Thanks for the tips anyway! Will surelyl remember that for the next time.

Re: Houdini voronoi to Soft - disconnected faces?

[Fabricio Chamon]

thanks Christopher! I tried using divide + the scale/rescale stuff...even
so I'm still not getting 100% reliable results as you noted.

On top of that there are many issues with alembic importer in softimage
It is buggy and hangs/crashes randomly (with the fractured meshes coming
houdini I have to say...didn't have any troubles like that in other
scenarios)

Ok. so here is an overview in case anybody else needs to transfer houdini
fractures back to softimage:

- .obj always import ok (doesn't crash), but internal faces are always
disconnected
- .abc imported through built-in importer sort of works (a progress bar
hangs at viewport, I have to click cancel, but everything is there). Welded
faces, which is nice, BUT messed up (stretched) UVs in some spots. Also, it
introduces all kinds of wierdnessess in the scene, so totally not
recomended.
- .abc imported through exocortex crate works reliably (doesn't crash, no
buggy behaviors). Welded faces, BUT no UVs (well it comes with a strange UV
that is not usable). Retains inside/outside groups from houdini (stored as
clusters) which is a big plus

So in the end the "easiest" way I found to transfer these meshes is to
export data as alembic through the ROP Alembic Output node (ogawa or
whatever, does not really matter), then import into soft with crate and
finally transfer the UVs using gator. (yeah terrible for dense meshes).

Re: Houdini voronoi to Soft - disconnected faces?

[Fabricio Chamon]

Well, unfortunatelly soft crashes everytime I try to import this alembic
mesh from houdini... so I went for objs.

And I'm afraid I can't merge them in Soft because a) it will take quite
some time as the whole geo is dense and b) I'd have to leave a gap between
the pieces or else any adjacent pieces would get merged together... and I
want them to be single pieces.

is that an export thing ? Because it works nicely inside houdini...

Houdini voronoi to Soft - disconnected faces?

[Fabricio Chamon]

Hey gang,

I'm doing a voronoi shatter in houdini and want to bring the result back
into softimage (exporting .obj to Soft 2015 SP2). The outside pieces are
disconected from the inside pieces, like this:

[image: Imagem inline 1]

I'm pretty sure it's me doing something wrong in houdini... My setup is
really simple: Import alembic mesh > vdb from polys > scatter > voronoi
with those points. Already tried to mess with all the voronoi parameters
and add a fuse node at the very end just before exporting. But I can't find
a way to have the outside/inside faces merged for each piece.

any hints?

Thank you

I remember having some problems like this in the past.. what is your scene

Re: Exploding fractured mesh

[Fabricio Chamon]

If you are keen to staying in softimage Momentum + implosiaFX should pretty
much serve all your needs. As Simon stated it will be not as stable as
houdini, but I've done some pretty decent setups with it.. some
intermediate ice skills and an understanting of the whole workflow of
momentum is needed, but for the kind of effect you described it should not
be too hard to get started... let me know if you need a hand and I can
create a quick setup here to send you.

Hey Nicolas, very nice! I'm particularly interested in the mocap suit. Does
it work well? How is the setup/calibration time? Any pros/cons? I can see
in the perception neuron website that you have to be extremely carefull
with your calibration or the system really will not work good enough. How
is your experience with that?

 Hi guys,

 I just want to share one of the projects I'm developing using the
 GearVR and a mocap suit.

 In short I'm walking inside a VR environment using the mocap suit to
 walk around and interact with the environment

 GearVR Test Demo 

 I'm using a Samsung Galaxy S7 Edge and the Noitom Perception Neuron
 Suit, and all the data is sent to the smartphone via Wifi...a bit laggy,
 but considenring the setup I'm quite satisfied by the results.

 I've shared the entire project on the UE4 forum
 
 if someone want to test the scene

 The video shows just a very simple environment, but future updates will
 include more content and features.

 I'm not planning to focus on games using this setup, but I guess that
 this is a good way to show everyone what I'm doing.

 Best Regards

 Nicolas Esposito

shameless plug - Fabricio Chamon

[Fabricio Chamon]

Hello fellow softimagers! (Short text, I promiss...)

Sorry for the self promotion, but there's no other place I know that will
like my softimage skills. =)

After ~10 years of fixed contracts, I finally got into the field for
freelance working.

Generalist, with inclination for fx/simulation/rendering/techy stuff.
Strong ICE knowledge. Also have been working on Maya lately, doing lots of
hair (xgen/yeti), crowds (golaem), particles/fx stuff. Arnold for render,
nuke/after effects for compositing.

Recent work here: www.fabriciochamon.com (reel is on the way)
Tools/making-of videos here: www.vimeo.com/fchamon

If you need a hand on any task, please feel free to drop me a line at
fabricio.cha...@gmail.com

Thanks for your time and help over all these years! Greatly appreciated.

Re: Momentum / implosiafx plugins

[Fabricio Chamon]

if I can recall, plotting was a feature pre-alembic. It got discontinued
once alembic took place.

Now there we have a killer combo: implosia + momentum + crate (easy retime
tools), all for free. I bet this is far better than MANY paid comercial
plugins out there... =)

Re: Momentum / implosiafx plugins

[Fabricio Chamon]

Hey thanks a lot Oleg!

Awesome tools, I love the IFX ice shatter nodes, they open room for some
mindblowing stuff

Btw where are you puting your efforts right now? Maya? Houdini? Fabric?

Cheers!

sorry or the confusion..StructureType being 1 is correct as the context is

GetICEAttributeFromName("Orientation").DataArray.toArray() is giving me a

Changed ICE Orientation attribute access from sdk?

[Fabricio Chamon]

hey gang,

in Soft 2014 I had this line of .js code:

pointcloud.ActivePrimitive.GetICEAttributeFromName("Orientation").StructureType

that returned -> 2 (*siICENodeStructureArray*)

now in Soft 2015 it returns-> 1 (*siICENodeStructureSingle*)

any hints? How may I access the particles orientation array ?

thanks a lot!

 Hi Gang,

 After a very successful and long festival stretch our graduation short
 film "Wrapped" is finally online. It's been a while, but I felt I needed to
 share it on the list since I've gotten a lot of useful tips and help over
 the course of the production. Thanks to everyone who contributed!

 The whole project was mainly done in Softimage and Arnold and I'm happy
 we can finally share it.

Re: 1 texture per polygon

[Fabricio Chamon]

yes, but then you are limited to a few images, and it does not scale
procedurally to hundreds of images for example...but if just a few images
already do the work, then you can use the multi-color switch I believe.

looks like the "Time Source" parameter on the image file nodes does not

OT: sequence file browser

[Fabricio Chamon]

Hey guys,

I'm constantly looking for a decent file browser that can handle file
sequences (read softimage-like collapsed/expanded views), and that works
for any file format. Its for general file checking only, I don't really
need to open the sequences...anyone ?

It takes some patience to check for missing files inside huge sequences,
not big deal but would be a time saver to have a simple browser that works
like SI for image sequences.

thanks!

Re: Feather System

Hi Morten, thanks for the feedback.

It is already possible to create simulated feathers with syflex (or

here's a rough test: https://vimeo.com/118137118
(I'm cheating on the the ruffling feathers - they are not really simulated,

Re: Dot Product on Rendertree?

[Fabricio Chamon]

hey Matt, thanks a lot for the detailed explanation and examples! that's
exactly what I neeed.
much appreciated.


2014-08-28 18:48 GMT-03:00 Matt Lind ml...@carbinestudios.com:

 Updated version:



 Vector_state à vector-Vector à Vector_Coordinate_Converter à
 Vector-Scalar à Gradientà Surface

 (normal)   (negate) (Vector, to Camera)(Dot
 against -1,0,0)(scalar input,[-1…1])





 This works in similar fashion to the method I submitted previously.  The
 main difference being  the normal vector is dotted against the camera’s –X
 axis to provide the directional information.



 If the viewed normal aligns with the camera’s –X axis, the dot product
 will return -1 (red).

 If the viewed normal vector aligns with the camera (points to the camera),
 the dot product will return 0 (cyan).

 If the viewed normal vector aligns with the camera’s local X axis, the dot
 product will return 1 (yellow).



 The output of the dot product drives the gradient.  Just make sure to use
 Processing  Mixers  Gradient and not Texture  Gradient.  If you want to
 make the output more accurate, zero out the Y component of the normal
 vector after it’s converted to camera space, but before doing the dot
 product.  Then normalize.  That will eliminate the vertical component.





 You want to avoid using expressions in render trees as it can slow down
 performance and cause other unwanted side effects.  Mental ray does all
 computations in ‘internal space’ which is largely undefined.  Softimage did
 it’s best to ensure that for lights and cameras, internal space is
 equivalent to world space.  So when the ‘vector_coordinate_converter’ node
 is used above to convert the normal to camera space, what it’s doing is
 converting the normal from world space to the local coordinate space of the
 camera.  However, it should not be assumed that internal space always maps
 to world space, because it doesn’t.

 *Subject:* RE: Dot Product on Rendertree?



 You cannot get your desired result with only a dot product because in
 order to differentiate between facing left and facing right, you need
 directional information.  A dot product only gives the cosine of the angle
 between the vectors, not direction.



 Based on your description, I’m assuming you want to drive color based on
 the surface normal relative to the camera.  To do that is fairly simple.



 1) Get a vector_state node and set it to ‘normal_vector’.  This is the
 surface normal at the intersection point.



 2) Get a vector_vector node and plug the previous node into
 vector_input1.  Set the operation to ‘negate’.  This will flip the normal
 to point away from the camera (assuming it’s a front facing surface).



 3) plug the result into a vector_coordinate_converter node, and set ‘type’
 to ‘vector’, then set ‘transform’ to ‘to Camera’.  This will treat the
 normal as an orientation vector and re-describe it in the camera’s
 coordinate space.  We do this to isolate the normal vector’s X-axis to make
 it easy to determine if it’s facing left or right relative to the frame.



 4) Plug the output of the vector_coordinate_conversion node into a
 ‘vector_to_scalars’ node.  This will give us access to the normal vector’s
 X, Y, and Z components.



 5) Plug the ‘X’ output of the vector_to_scalars node into the ‘input’ port
 of a gradient node.  In the gradient shader, go to the ‘input’ tab and set
 active range to [-1…1] and set input type to ‘scalar input’.  Finally,
 adjust the color gradient markers so the left end is yellow, the middle is
 cyan, and the right side is red – the opposite of the default arrangement.
 If you do not want to futz with the color markers, then invert the ‘active
 range’ on the input to be [1…-1].  I don’t recommend inverting as it’s
 non-standard math and while it’s perfectly fine for this simple prototype,
 it’ll cause headaches in a production pipeline as it’ll be a source of hard
 to find bugs from stupid logic.

 Hello,

 i was wondering if someone had tracked down the issue in Fabricio Chamon's
 superb strand tree compounds that stopped it working in  2014? Failing that
 would I be able to find a list of ice nodes that changed between 2013 and
 1014 so i could at least have a chance of replacing / rebuilding just the
 bits that changed (before i rebuild them all by hand - and then discover
 that I've still not fixed it)

 cheers,

 Hey Fabricio, i'be bumped onto that also, in my case it was the Mesh
 Splitting kicking in. It separates dense meshes into separate objects
 before passing them on to MR. Therefore, some shaders get artifacts, like
 volumetrics and bumpmapping also.

 Real headache but easy fix...

 Under MR  Optimizations, look for Mesh Splitting Factor, increase the
 value up to infinity and be happy :D

 I'm trying to do some volumetrics in mray, but the shader is giving me all
 kinds of wierdness on heavy meshes. Have anyone experienced this before ?



 For the sake of simplicity, I have this test scene with only one default
 sphere. If I crank up the sphere U/V subd to 200, it starts to show some
 strange black areas. At subd 300, it renders all flat.

 I'm guessing it's not a lookup table cell size problem...tried very small
 values, and the volume renders almost completely solid (when it works).
 here's some images to illustrate:

 I really need dense meshes because I want the fine control over the volume
 silhouette to be on the mesh itself, not through shader trees.



 anyone ?

  Hello List,

 over the course of one year, a small team here at Elefant Studios
 created a CG head replacement for a talking owl, set extensions for a
 steeple, talking ‘haunted’ paintings, background matte-paintings as well as
 general shot compositing in 111 shots for the movie ‘The Little Ghost’ (
 http://www.imdb.com/title/tt2186566/). The movie is Alain Gsponer's
 adaptation of a children's book from Otfried Preussler.

 The main tools we used on this project were Softimage, Maya, Mudbox,
 Nuke, Arnold and our in-house asset-management and pipeline visualization
 tool. Maya for Modeling, Rigging and Animation, Softimage for Feather/Fur
 Grooming, Scene Assembly and Lighting/Shading/Rendering. Mudbox was used
 for Texture Painting and Sculpting. Nuke was used for Compositing and
 Arnold as the rendering-backbone through SItoA.
 The biggest challenge was the creation of a head replacement for a
 talking owl. As some of the shots were planned as close-ups we had to
 consider a highly detailed implementation. Autodesk Softimage’s ICE system
 was used to model feathers in high resolution in any desirable shape.
 We developed tools using ICE to enable us to place feathers and hairs very
 accurately, always preserving the defined shape of the head and neck from
 animation. All feathers were rendered as Curves in Arnold. Lighting was
 done with Skydomes and textured Quadlights.
 We created a high detail steeple on top of a building as well as
 various extensions to tackle the limitations from the filmed set.
 Everything was rendered with high detail displacements, GI, Skydomes and
 all the other nifty features Arnold offers.

 Big thanks goes to Jonah Friedman from Psyop ( we used some concepts
 from his Ruffle system ), Daniel Guimard for his work on the steeple,
 Vivien Guiraud and Patrick Graf for the animation, Yukio Satoh for a nice
 animation rig, Miklos Kozary and Stephan Schweizer for the compositing and
 all the others who helped out.

Re: Strand length on the rendertree

[Fabricio Chamon]

sorry for the confusion. by strands and not using ice I mean using soft
built-in Hair system. On the rendertree, Scalar State set to Barycentric B
outputs a normalized length, which I don't want.
I've implemented something similar to Leonard's tree in ice, but it really
doesn't help, unless there's a way to transfer all the render hairs (not
guides) to ice strands. I've tried melena and it works great, except
there's a 1 million hairs limit, plus it keeps a live link with the
original hair that hurts performance badly (It was not designed to work
this way I believe). Maybe I'll have to dig into c++ and use the render
hair accessor to bake xsi hair into a new pointcloud and do the gradient
math on the icetree.

Hi guys,

is it possible to access the absolute strand length value (in SI units or

need strands to pick a value from the gradient based on their actual length
(strand with length=1 goes from black to white, strand with length=0.5 goes

Not using ICE, so I have to calculate at render time.

Re: MT Strand Extrude for 2013/2014

[Fabricio Chamon]

Don't ask me why, but if I add a TurbulizeStrand (with very tiny strengh
(0,001)) after the Strand creation, it all goes well and the polymesh gets
generated.

Probably because the first strand position is aligned exaclty on top of the
particle position, then it cannot calculate the tangent vector. The
turbulize node shifts the two vectors a bit, and the tangent calculation is
then validated.


2013/7/19 olivier jeannel olivier.jean...@noos.fr


 I found a little disfunction when using the stCreateStrandset of compounds.
 Sometimes, if you're creating strands a bit differently than the usual way
 (EmitFromGeometry + CreateStrand) it can happen that the generated polymesh
 contains 0 (zero) polygon.
 (It happen to me when emitting from curve (indstead of point) and also
 when emission was set to TotalNumberOfParticle, and other exotic cases that
 I can't remember )

 Don't ask me why, but if I add a TurbulizeStrand (with very tiny strengh
 (0,001)) after the Strand creation, it all goes well and the polymesh gets
 generated.

Re: Pointlocators out of sync

[Fabricio Chamon]

+1000 to what Vladimir said.

Cached locations always loose contexts and does not resolve correctly,
giving you red nodes all over the icetree.
On the other hand, from my experience reinterpreting locations also crashes
frequently. So, keep incremental backups! =)


2013/6/26 Gustavo Eggert Boehs gustav...@gmail.com

 Thanks Vladimir, your approach is solid :D
 Just what I needed to keep me sane!


 2013/6/26 Vladimir Jankijevic vladi...@elefantstudios.ch

 that's a no go. I think the simplest way is to have a non-deforming and a
 deforming mesh in your scene. first take the ref from the non-deforming and
 then reinterpret the location on the deforming. this can be built really
 easily  with a switch.
 I never managed to cache locations safely. Softimage behaves really weird
 concerning location interpretation.

 Sadly I get quite an incosistent behaviour with this locators across

Re: Looking for exporting tips with ICE topology - SI2014

[Fabricio Chamon]

Probably hitting the ice optimization problem? Make sure your UVs are
correctly set by putting a log values just before your set data node.


2013/5/9 Eric Cosky e...@cosky.com

 Hi,



 I've recently started using ICE modeling to help with some low poly models
 with tiny textures. The general idea is to make very small components, set
 up the UVs as needed, then make a larger model that is composed of many
 copies of the component. I like this approach because it lets me adjust
 pieces after they have been put into place, including the texture
 projections which will be propagated at any time in the future when the
 original model changes unlike how clone seems to work. With the low
 poly/low
 res textures, it's not always obvious what the best look is going to be
 until it's all together so being able to edit everything including texture
 projections is pretty helpful to the workflow. Here's an example:
 https://dl.dropboxusercontent.com/u/36497436/misc/ice-model.jpg - the ring
 is made of the two parts shown in front, and it's using just a fraction of
 a
 128x128 texture. If anyone is interested in looking at the scene, it's
 here:
 https://dl.dropboxusercontent.com/u/36497436/ThunderMoon/Portal.zip





 The modeling technique generally works as expected, but I am finding that
 the UVs are not reliably available in the final ice model during export.
 For
 instance, the inner ring was exporting the UVs correctly, but not the outer
 - all UVs on the outer were the same (I think [0,1], possibly the original
 projection values which ICE was supposed to override). The exporter is
 written in C++ and works correctly for exporting UVs on normal models, but
 it seems like I have to freeze the modeling to get the UVs to be available.
 Is this a typical thing to need to do with ICE modeling? Hopefully freezing
 isn't a requirement for proper export. The strange part about it is the
 inconsistency between the two ring parts, how one of them exports the uvs
 properly and the other doesn't despite being identically configured (as far
 as I can tell). This isn't a huge problem, just a workflow thing I'm trying
 to understand  optimize before diving into more assets. If freezing is
 required, so be it, would be nice to know if I'm just doing something wrong
 though.



 Also, I am occasionally finding SI2014 gets into a strange state where one
 or more of the ICE models just doesn't appear. It is selectable, but has
 zero triangles/verts. When this happens the only thing I found to make them
 reappear was to move the object in the hierarchy, which of course seems
 like
 a bug but perhaps I am just missing something here. If nobody else is
 seeing
 this I wonder if it has something to do with the use of RTShaders. I was
 thinking perhaps shuffling the current frame to/from the first frame of the
 scene might help but it doesn't, the only thing that fixed it for me was
 moving the objects in the hierarchy.



 Any tips or suggestions on typical problems  workarounds for dealing with
 ice models in the context of exporting the assets would be appreciated,
 thanks.

Re: ice crowds and rendering

 Yeah, I have done that a gazillion times and they still seem to disconnect
 when rendering.  Though I have been jiggling with the materials quite a bit…
 

 However I’ll try again as my experience seems to indicate that things

 one could create a script that would execute every frame and snap those

 Hi Jeff.. This is a known issue for sure.

 I work around the issue by doing the following,

 I generally just get in and edit the texture projection in the render tree
 per image node on each actor copy. You have to point each image to the
 TextureProjection UV available to each ActorCopy.) 

 On the Mesh Proxy you have to set the UV's to the correct projection in
 the Set Mesh Proxy compound in the ICE tree.

 Once I do that, I have no problems with textures showing on rendered
 sequences.

 ***

 I have been working with crowds and am excited about some of the results I
 am getting but have one nagging problem that I have not been able to
 overcome.

 That problem has to do with rendering and the fact that texture
 projections seem to become broken/disconnected from the material when the
 job distributed to a farm (we are using RR).
 When submitting jobs as a continuous sequence that begin on the first
 frame (frame 1) all seems to work fine.  However when the job is spread
 across machines the textures are broken.

 As a quick overview of my setup I am using an random integer to drive a
 color switch in the render tree which basically selects the appropriate
 texture.
 As I said this all works fine as long as I render from the first frame of
 the sequence.

 Just a guess but I suspect this has something to do with the fact that the
 texture projections are created when the ice tree initializes on the first
 frame.
 Has anyone else experienced this and maybe know of a fix or workaround?

 I am wondering if I can tweak the scene or render software somehow to
 force the simulation to begin on frame 1 for each frame rendered?
 Seems I recall some scripts that may do this but I have been unable to
 track any down.

 Any suggestions much appreciated

  ...but how to access the string array (values) of this attribute?


 2013/2/15 Stephen Blair stephenrbl...@gmail.com

  Hi



 It is a string.

 // Using one of the CrowdFX sample scenes:

 SelectObj(Pedestrian_Mesh.Actor_Copies, null, null);
 o = Selection(0)


 //o.ActivePrimitive.Geometry.GetICEAttributeFromName(Materials).DataArray.toArray()
 // WARNING : 3391 - This ICEAttribute doesn't refer to a 1D array:
 Attribute: Materials

 a = o.ActivePrimitive.Geometry.GetICEAttributeFromName(Materials)
 LogMessage( a.DataType )
 // INFO : 131072

 thanks guys! I rebuilt the scene and started incremental saving
 too...Really hard scenario to work on, I hope this will get fixed soon.

  Another question: it seems really easy, but I can't get the ActorCopies
 ICE materials array via script. I feel it should be a singleton(which it
 is), 1D Array. This js code:


 oActorCopies.ActivePrimitive.Geometry.GetICEAttributeFromName(Materials).DataArray.toArray()

  returns:

  This ICEAttribute doesn't refer to a 1D array: Attribute: Materials

  and


 oActorCopies.ActivePrimitive.Geometry.GetICEAttributeFromName(Materials).
 *DataArray2D*.toArray()

  returns

  ERROR : Type mismatch

  any clues ?

 Yeah workgroups really help. I'm a hack when it comes to python scripting,
 so most of the stuff I end up writing for myself I shoehorn into a few
 custom menus that live in a workgroup, which also contains assets like
 models and rigs. I've never even explored packaging stuff as addons (I
 should). I just carry the workgroup around... :P

 Nice stuff guys! I have plenty of little scripts here and there too,
 probably similar to ones already mentioned, or ones i used at various
 studios and had to rewrite for myself. Anyway I'm not sure the best way to
 organise it all online, but fortunately with soft workgroups make life so
 easy at work... Compared to wanting to be organised in max, I usually
 just give up :)

 Cool, thanks for sharing that Fabricio, it's brilliant.

 Here's one I have in my personal menu - creates an annotation log of
 distance measurements. Select two objects and run, places the distance
 between the two in an annotation, or adds to an existing annotation.

 I made it during a time when I was doing a lot of DoF work, and it's
 turned out handy ever since.

 Not packaged up in any particular way, pretty much ripped right out of
 my menu ;)

 For what's worth, here's my CVO (Custom view opener) dual monitor

  Rename to CVO.js (can't attach js files!)  Copy to
 application\plugins  Map it to any key combination (mine is always
 ctrl+[original shortcut]).

 - Screen resolution must be set inside the file (currently is
 1920x1080).
 - you may also adjust some pixel offsets to better accomodate for your
 OS layout.
 - viewname has to match any file from the application\views folder

 You can register more commands to it, I always do:

 - icetree
 - rendertree
 - script editor
 - object view (ctrl+alt+1)
 - fx tree  (ctrl+alt+2): opens fxtree maximized at monitor 1 and

 Let's share the good stuff, definitely!

 Which reminds me: shouldn't ol' Netview be the easy-to-access

 What happened to it, and why?

Re: Toggling toolbar buttons

[Fabricio Chamon]

Hey Gustavo, does it have to be a button ? If not, here's a very nice trick
from Jeremie Passerin:

var cp = ActiveSceneRoot.AddCustomProperty(MyCustomPSet, false );
var layout = cp.PPGLayout;
cp.AddParameter3(myBooleanParam, siBool);
item = layout.AddItem(myBooleanParam, , dscontrol)
item.SetAttribute(class, button)
item.SetAttribute(siUICaption, Toggle Button)
item.SetAttribute(siUIStyle, 0x1003)
item.SetAttribute(siUINoLabel, true)
inspectObj(cp);

...then put your code under the _OnChanged callback.

Re: Ice Topology | build mesh from pointcloud trinagulizer thing

[Fabricio Chamon]

There's no need for ice topo, you would over complicate things..can't you
use the built-in polygonizer ? It can handle nulls too.
but probably a faster/better workflow would be to put all the nulls into a
group, then emit particles on the global position array and polygonize
that...

Re: Lagoa_Density not cacheable

[Fabricio Chamon]

...happens everytime to me.
What I always do is to init the custom variable on the right context
*before* loading the cache (cahe on file node).
It prevents the rest of the icetree from screwing up with your attribute.

 Hi Sebastian,

 if it is just a color gradient by particle density that you are after then
 it is really simple to get this with a Get Neghbours  count  rescale
 range  gradient

 ie this https://vimeo.com/1618403

 it is a fast realtime calculation (as long as you set the search distance
 to a reasonable level!) than can be applied in the modelling stack of an
 ice tree to an already cached simulation affecting the color

 if its something else required from the actual part of the Lagoa
 Simulation then I have no idea of how to get it without simmming again.

 I could try to write this attribute into a custom attribute, but this is
 a heavy simulation, i don't want (and don't have the time) to re-sim.

 any hints how i could fix that would be much appreciated.

Re: Lagoa_Density not cacheable

I mean, sometimes you cache it in the right context but ice refuses to read
it...that's my case above.

Re: page turning effects with ICE

[Fabricio Chamon]

you can concatenate your strings: prefix + integer + suffix. Now for
integer - string conversion there is Eric's emTools freely available:
http://www.mootzoid.com/wb/pages/documentation/emtools.php#IntegerToString


2012/11/18 Adam Sale adamfs...@gmail.com

 Hey guys. Thought I would put this out there.
 One of my artists is creating the effect of a page turning effect on a
 book. The idea is to have hundred of pages being flipped magically by
 another character.

 The easiest way I found without using ICE was to take a single page attach
 a series of chains to it, animate a singe page turn, cache it, then
 duplicate the page, and offset the resulting caches. Works really well,
 especially if I use 5 or 6 different chain animations to vary things up.

 We wanted to try and use ICE to see how we could come up with a compound
 for this mixing vector nodes and shome shapes.

 So far we have been able to achieve most of what is needed with rotate
 vector and mixing in a few target shapes that activate based on angle.

 What we would like to do is construct a string, for example

 polymsh.cls.shape.pageOneFlopLeft_Integer.positions where
 Integer is a value read off a custom parameter from a given object

 If anyone has a sample Ice tree that does something like this, or can
 point me to a sample scene or reference that may help me work through this,
 I would be most grateful.

 Adam
