Re: avi corruption

[Oscar Juarez]

As far as I remember avi has a file size limit, can't remember if it was
2gb or 4gb, is your sequence long enough that will output a file that big?

I put your foreach blocks in compiled blocks and it shaved 0.5s :D

It is indeed pretty fast, 5.1s including scatter. Without the scatter is
2.0s

Re: Multiple objects copy

[Oscar Juarez]

I did a simple test with the compiled bock, I'm copying 5 packed primitives
to 100,000  points, performance monitor gives me 3.1s on an i7, 4 core @
3.6 with HT, I noticed that if you visualize any node inside the compiled
block, the cooking time is longer. Also measuring the with compiled blocks
on the performance editor should only show the compiled block nodes, it
doesn't any node inside of them.

Keep your camera without any rotation in X and use optical shift in Y in

I think for reference frame you need to use the Polyframe SOP to generate
your attribute, there is no intrinsic attribute as far as I know

Hey Jordi,

Very nice, will gladly help with translation to Spanish. Will send a mail
to the beta either way.

Thanks!

Re: [Sidefx-houdini-list] vop addprim

[Oscar Juarez]

You have to use addvertex to actually add the primitive. So for creating a
primitive line with two points, you have to add points one add primitive
and two add vertex. Addvertex expects one primitive number and one point
number. Remember that to fully have a primitive you need the vertices too.

Re: Need help - Scene crashing on the farm - renders in the UI

[Oscar Juarez]

Maybe for the sake of decoupling softimage completely but depending what
you are rendering (static or moving), you could try to convert this whole
model to an ass file and render that instead of the model itself.

Re: houdini question (and where to ask)

[Oscar Juarez]

I would like to be proven wrong, but that would be the way, I mean in your
second pointvop you don't need to add another noise, your noise is already
saved in an attribute, when you promote just check off delete original and
you can access the same noise. Also noises have specific output ranges,
they come in the documentation, so you can always add a fit node to change
your range to what you need, in the geometry spreadsheet you can also sort
by value so you can see max and min.

If you press X with your mouse over the noise output it will add a
visualization node, you can visualize on the viewport or in the geometry
spreadsheet the values. I know its not the same but as far as I know their
is no way to do the same as the get maximum in set node in a vopsop context.

 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...

 thanks!

Re: houdini question (and where to ask)

[Oscar Juarez]

For your second question, the equivalent for an fcurve node would be the
ramp parameter node, set to float values. You have to go up one level to
adjust the actual fcurve.

And for your last question, I might not be that helpful but in the SideFx
forums there is a forum specially for softimage users which might be a good
place to ask about equivalent tools between softimage and houdini. I find
it that asking houdini questions here keeps also things moving, but some
people might not like it.

cheers.

Re: houdini question (and where to ask)

[Oscar Juarez]

As far as I know inside the pointvop  context you can't do it, but you have
the attribpromote nodes, that let you promote point attributes to detail
for example and get the maximum value or minimum or whatever you need. You
save it to another attribute which you can then access on the pointvop
context.

Re: A gem of a tutorial

[Oscar Juarez]

The geometry SOP is just a container, it is a node that lives in the Object
context of Houdini, much like any object in Softimage. When you dive inside
this node, it would be like going inside the construction stack of
softimage, every node inside could be thought as an operator in the
construction stack. It is not exactly the same but it helps to see it like
that.

He deletes immediately the node, because the default node that comes with
the geometry is the file SOP which allows you to load external geometry,
since he is creating geometry from scratch he doesn't really need it.

Hope it helps.

Re: [Houdini] Working with strands the Softimage way

[Oscar Juarez]

There is no strand concept in Houdini like in Softimage, Strands in
Softimage were Array attributes per point. In houdini aeverything is
points, as you have already seen, polylines would work something like
softimage strands, but they are still points. There is several ways to get
attributes per primitive (polyline) so you can process them based on
something resembling a point id. The connectivity sop will add a common
value to all the points belonging to the same primitive.

You can also add an attribute to the length ratio of your polyline, it can
be done through an expression or using the resample SOP you can turn on the
generation of the curveu attribute, you can turn on resample by polygon
edge, with maximum segments of 1 and max segment length option off, that
way the attribute is generated without actually resampling. Other better
way would be with a point wrangle just add this "f@curveu = @ptnum /
(@numpt - 1.0);"

One way to populate strands would be creating a base line, then using the
copy SOP to copy it to a set of point positions which could come from a
scatter node. Then you can inherit a lot of attributes from the points
themselves. And set all your initial attributes on your base line.

The thing to remember is that there is no such thing as a strand context,
you have points, primitives and vertices, and you can move around data
between these elements all the time. Hope it helps to start.

Is your decimal mark ","? If that is the case, I think it doesn't work, you
need to have "." as decimal mark.

Also you can visualize time dependency, it will make the nodes glow a very

Re: Motionblur on geometry from Houdini via alembic?

[Oscar Juarez]

I just find out that if your attribute is called v crate wont read it, I
used an attribute rename node to rename it as 'vel' and turn on the custom
checkbox in the alembic node and it works.
Here is a small sample, just put the files in the root of a softimage
project:

https://www.dropbox.com/s/00f09gc1zxpvq70/abc_vel.zip?dl=0

Hope it helps

Re: Motionblur on geometry from Houdini via alembic?

[Oscar Juarez]

If its point count varying geometry then your motion blur should come from
a velocity attribute. That error message to my understanding means that
since the points counts don't match between frame intervals motion blur
can't be calculated by Arnold, that's how it's done by default.

If you have your velocity attribute from Houdini then you should put it in
the PointVelocity attribute on an icetree in the object and in an
arnold_parameters property turn on use ICE PointVelocity for motion blur.

Re: correcting shapekeys

[Oscar Juarez]

If I understand correctly you already have some shapes correcting
deformation for example on the arms, and now you want to add another shape
that corrects something in the mouth, and when you try to save this shape,
it is wrong because also includes the shape correcting the arms?

If you install gear, there is a very nice script, that lets you select some
points and a blend shape and lets you remove the shape contribution of
those selected points so you isolate only the part that you actually need.

[Oscar Juarez]

I had an external artist using Windows 10, and I couldnt make
PyQtForSoftimage work on it, if I remember right it was this out of range
error. I had to leave it due to time constrain things, and that we don't
use windows 10 ourselves. But the PySide implementation that comes with
Shotgun toolkit worked alright, probably that doesn't help you at all but
just to let you know that I also found that problem with win 10.

external Python 2.7.3 / PySide 1.1.3 / PyWin 218, the same config works
fine in windows 7

Maybe the custom tool in fusion might be interesting for you, you can do a

Re: Arnold shaders, interactive oppacity on Alpha?

[Oscar Juarez]

That is something that Arnold has never done, Refraction always comes with
solid alpha. Opacity on the other hand works as you want but probably is
not what you are after. The way to handle this is to render with your
background in 3d so it's seen through the refraction.

Re: Change object visibility with another object?

[Oscar Juarez]

You could try something like this:

if any point is inside a volume the visibility get turns off. You could
play with averages and thresholds so it fits better to your needs.

Re: Exporting Pointclouds to Houdini using Alembic.

[Oscar Juarez]

Custom attributes pass as an array detail attribute, or at least in my case
was like that, so you will have to do something else inside houdini to pass
them as per point data.

What I do in this case is model a fast "cage" using the same geometry or

weights to all the layers.

Re: Knowing if you are front-face or back-face of a polygon.

[Oscar Juarez]

Get closest location to the grid, subtract this location position from the
particle position, dot product to the location normal, depending on the
value you can know if it's back face or front face.

Re: How To Suppress Action Connection Resolution Dialog

[Oscar Juarez]

Don't know which version you are using, but this is copied from the 2014
docs, the last parameter from AddClip, tells the command to ignore missing
connections and the dialog itself:
IgnoreMissingConnectionsBoolean
If
true, ignores missing connections by skipping the connection resolution
dialog.

Default Value: False

A bit OT - Kraken issues

[Oscar Juarez]

Hello Eric and Phil,

I don't know if this list is the correct place to send issues and questions
about Kraken, if not, where would be a good place? On the github page for
the project?

Right now I started testing it and everything works as expected, opening
the editor, building guides and building rigs.

The rigs work, although in Softimage much slower than in Maya at least with
the Fabrice rig, if I save the scene and close it and re-open, the rig
stops working, still interaction is like before, but the deformers are not
moving anymore, I guess it is still evaluating but something gets
disconnected.

In maya this is not the case, I can save and re-open and everything still
works. I checked and the spliceOps in the cmpOut nulls and deformers are
still there, but somehow they are not working.

Does this ring any bell? I'm using Fabric 1.15.2 and the latest Kraken.

Thanks in advance
Oscar Juarez

Re: Alembic Crate workflow - what do you guys do?

I agree with Simon, if it's only for rendering I would export just the
geometry with flattened hierarchy and transforms, will be a light cache
that way if you don't have any deformations.

Re: ICE Syflex conversion to animation clip?

[Oscar Juarez]

If you are losing your "mySpriteID" when caching, visualize it in the
viewport before caching, ICE optimizations sometimes will throw away
attributes even if you specified that they should be cached, by visualizing
them you are forcing ICE not to throw them away.

Re: Alembic workflow?

[Oscar Juarez]

Yes that is Softimage to Softimage, but it would also apply from Maya to
Softimage, you can also get Crate for Maya, the only consideration you must
have is your naming, and the paths inside the alembic file, with crate you
are able to flatten the hierarchy and avoid exporting the parent name so
you end up with an alembic file which only contains your mesh objects in
it, so then you can apply it relative to any model or container you want.

For example you have this in maya
GroupName
- Mesh1
- Mesh2

You end up with an alembic file which only contains the meshes.
- Mesh1
- Mesh2

Then with crate you can select to which container to apply it and you just
have to worry about your mesh names.
ModelName
- Mesh1
- Mesh2

We have some tools to avoid doing this manually for several assets, but if
you keep the same container names in both Maya and Softimage you can export
one alembic file for diferent assets which include the container name.

Re: Alembic workflow?

[Oscar Juarez]

What we do with Crate is we have a rigged asset and a render asset, the
render asset is reading the geometry from an alembic file and we load as a
referenced model into the lighting scenes, then we apply the alembic cache
to that, Crate is smart enough to do point cache or transform cache, so
even if it's a lot of points and they are not deforming they should save
the only transformations and caches should be small if you do a pure cache
file.

So you have two levels of referencing, softimage reference model which will
hold the objects and shaders, and the alembic files which hold the
transforms, point caches and geometries. I've had scenes where I have even
changed the geometry completely of an asset as long as your naming is
consistent everything should work.

If you load it through crate, and leave the op live, the geometry will be

Just a quick shot in the dark, constrain the lattice or parent to whatever

be relative to the head even if your lattice is being deformed too.

Re: How to fix degenerate polygons?

[Oscar Juarez]

The script only selects the bad polygons, also the one on the blog, they
don't do anything else, this will let you identify the polygons that are
the problem, but then you have to decide what to do. If the issue comes
from overlapping points maybe even a very small smooth might move them
apart and avoid the zero area without changing topology.

Re: How to fix degenerate polygons?

this should fix the script, it will select all the polygons that are wrong

si = Application
epsilon = 0.1

# Get PolygonArea DataArray (which is a tuple)
sel = si.Selection(0)
attr = sel.ActivePrimitive.GetICEAttributeFromName( "PolygonArea" )

Re: How to fix degenerate polygons?

[Oscar Juarez]

As the blog post says, degenerate polygons most of the time are zero area
polys, a filter points with a very small distance have solved this kind of
issues for me on the past, but since your geometry is deformed you have to
check if it doesn't break your plotted shape or if it doesn't break other
things.

Re: Crashing with unknown error message.

[Oscar Juarez]

I've had that error before, and was something with arnold crashing, the
alembic files were not really the cause of the error, and I only had it in
the farm also, so maybe check your configuration for arnold on the farm, I
can't remember exactly what was the culprit but it happened when I upgrade
arnold. Here is also a thread that talks about this.

Re: Parameter Bracketing doesn't work

[Oscar Juarez]

I've found out that doesn't work properly when you have commas as decimal
separators, here everyone has german keyboard and language settings and I
don't really remember if I found a way to do it properly but in my pc I
have point as decimal separator. But that's in 2014 haven't tried in 2015,
maybe it's something related.

The first weeks with them are a bit painful then everything starts coming

AttribWrangle nodes and how you have access to a lot of stuff.

Re: Particle caches go funky

Agree with Cristobal, I do the same a second cloud with the cache works
good, duplicating clouds that have a cache already loaded sometimes work
funky so I don't do it, also just to be sure that you export all your
needed attributes, visualized them on the original cloud.

We've been using Yeti converting grooms to curves, simulating long hair

Re: maya yeti to softimage

[Oscar Juarez]

Yeah loading the procedurals have it's quirks, but I think it's the most
straightforward way so you use directly the Yeti cache, because if you need
to make a change, you have to cache yeti and then export the ass sequence
again. Using the caches you just need to re cache Yeti and have all your
shading and everything inside Softimage, you can also load yeti rendereable
attributes in the render tree using mtoa user attribute shaders.

Re: maya yeti to softimage

[Oscar Juarez]

Yeti, to Zbrush to Softimage? You can convert grooms to curves but only
static, the groom is the guide curves and as far as I know you cannot save
a set of generated fibers. What we read in Softimage is the Yeti cache
through an Arnold standin property pointing to the yeti procedural instead
of an Ass file, which then the procedural grabs and generates the fibers on
rendertime, you don't use the grooms or curves at all inside softimage.

Re: maya yeti to softimage

[Oscar Juarez]

Sorry, I will be more specific, if you are rendering with arnold you could
use the procedural inside softimage, or export Ass file sequences from maya
and load them in softimage, either way you need to put some environment
variables so it works, but we've been doing it like that with good results.

If you have access to Houdini, I think there is several ways to re-order

Re: hair rendering

[Oscar Juarez]

min pixel width is disabled when rendering from a User view, it needs a
real camera to work. So always use one when working with hair.

 Yes its Arnold. No lens shaders, same render settings in all regions.

Re: How to offset instance animation in ICE?

[Oscar Juarez]

Set instance geometry, has everything you need, just be careful with how
many offset you create, each offset will create a new object for the
renderer, so if each instanced model or geometry has a different offset,
you will end up sending individual copies to the renderer an your memory
will rise to the roof.

Re: siComboBox

[Oscar Juarez]

your list needs to be in pairs of "label" and actual Value of the parameter.

so it should be something like

MatTypes = ["Mat1", 0, "Mat2", 1, "Mat3", 2]

Maybe some kind of user normals, clusters or are they connected in some way

Re: Edge Creasing and practice vs the modern day renderer. (Arnold, 3Dlight, Redshift...)

[Oscar Juarez]

>From Houdini docs.

Warning
The RenderMan renderer will directly use the Crease attribute applied by
the Crease Operation, but it will not be used by the Mantra renderer due to
patent issues.

 I've worked with assets from one studio coming to us converting from
 Max to Softime for Arnold. Edge creasing was horrible because it didn't
 carry over in the models. Obviously if you have end-to-end control of the
 pipeline it's not too bad but any transfer between packages (Zbrush,
 3DCoat, Mari) gives me the heebie jeebies.

Even if it takes longer as a general process, the review iterations are
much better and you end up with a better model. And you free your modeler
from the topology but be careful, the guy doing the re topo should know
what he/she is doing :D
