Re: [Nuke-users] Amateur Question: Transform Node after Source Image

[Howard Jones]

Yup like Ron says. 
Otherwise just for a start you will be blending screen and edge pixels together 
which makes the edge worse.

Re: [Nuke-users] Premult of Mask channel

[Howard Jones]

Always grade with an unpremult source with very few exceptions
So
If the CG is premuliplied then do
CG-unpremult-grade-grade-grade etc-premult

You can use the unpremult in a grade/CC  node but if there is more than one in 
a row it's easier to unpremult do ya grades then premult.

AW: AW: [Nuke-users] "Referencing" or "Instancing" groups of nodes

[Thorsten Kaufmann]

Hey Howard,

thanks. That would probably work. I was hoping somebody would come up with a 
"live" solution. One thing that needs updating i have toyed with is
Having the "virtual group" use a CMSPattern as input and writing a LUT as 
output. Then just slap in a VectorField where the "sub-tree" is needed.
As i am pretty much only talking color nodes that kinda works. But it is next 
to impossible to work with colors and grades if you have to click to update.

Regards,
Thorsten

Betreff: Re: AW: [Nuke-users] "Referencing" or "Instancing" groups of nodes

What if
1. When you create the node you actually copy a gizmo script to a location with 
a unique name. If it needs to work across all scripts rather than in the one 
script then I guess skip the unique name
2. Have an update button in the node which effectively rewrites that gizmo with 
all the changes and
3. replaces all nodes referencing that gizmo with the new one.

It would require stopping the user from making new uniquely named nodes, or a 
function that would (like force clone) set all similar nodes to only one 
version (and remove/archive the others?) of the external gizmo.
And it could check the script for the node and alert the user to whether or not 
they wanted to start a new version or use a copy(clone) of the already created 
version

Not as immediate but has the slight advantage that if you screw it up you could 
always go back to another version in the script until you update.

Would that work?

Thanks everyone,

i am aware of node-by-node workarounds. This is not what I need though. Compers 
might add arbitrary nodes at any point or time, and
preventing them from manually having to clone nodes around is the whole idea. 
So adding and removing nodes must happen automatically
too.

Hey,

I have never had any issues with cloning nodes corrupting scripts, but if you 
have it makes sense you avoid it. The other approach would be to copy the 
network, link all knobs to the "master" network and use python callbacks to 
have all other copied networks inherit the change.

I'm not sure it would work, but maybe give it a try?

Hi there,

i am aware of cloning, but you cannot clone groups. Also cloning has been an 
infinite source of agony here. Has this changed for 7? (Corrupt scripts
that can only be “fixed” by removing clones via texteditor). In addition there 
are python tools to create a linked copy as opposed to a clone, but that
also does not allow me to have a group of nodes being cloned. PreComp also 
won’t work because I need the ops to be in the script and editable

I believe cloned nodes does just what you are after? If you change the value of 
a clone it will also affect the "parent". Simply select and Alt+K.

I tried making a gizmo out a little network, but gizmos can't be cloned. At 
least not in 6.3.

Re: [Nuke-users] Re: Globally disable motion blur in the viewer?

[Nick Guth]

You could use something like this. It looks for motion blur knobs and disables 
it in the GUI. Alternatively, you can just set its value to 0, then before 
rendering set it back to a value.

x=nuke.allNodes()
for n in x:
 try:
  n['motionblur'].setExpression("$gui")
 except:
  pass

Typed it on my ipad, so tabs might not be properly spaced. Cheers.

Re: [Nuke-users] Trouble Importing my EXR with Layers

[Nathan Rusch]

Don’t forget that multi-layer EXRs have higher read overhead than single-layer 
files do, since layers are scanline-interleaved within the EXR file itself.

Until everyone starts using EXR 2.0 (including Nuke’s exrReader), separate 
sequences is still the more efficient option.

What I gather from your post is that you have rendered to multiple EXR's 
instead of one EXR with layers. This is actually my prefered way of doing it as 
a multichannel EXR requires you to shuffle out the layers anyway (unless you 
want to specify what layers to merge in every merge node eg.) 

If you are using V-Ray you pick exr (multichannel) as your output to get 
multichannel exr.

My prefered way is to just drag and drop the folder containing the rendered 
images into nuke, nuke will automatically identify the sequences and you are 
good to go.

Re: [Nuke-users] "Referencing" or "Instancing" groups of nodes

[Ron Ganbar]

Far as I remember:

   - Clone can on ocassion corrupt scripts. Happened to me a couple of
   times and was discussed on the forum a few times as well. Maybe it was
   fixed in 7 - don't know.
   - There's a pasteWithConnections script on Nukepedia, which does a Shake
   style clone. Not sure if that's the correct name for it, though.

Re: [Nuke-users] "Referencing" or "Instancing" groups of nodes

Hey,

I have never had any issues with cloning nodes corrupting scripts, but if
you have it makes sense you avoid it. The other approach would be to copy
the network, link all knobs to the "master" network and use python
callbacks to have all other copied networks inherit the change.

I'm not sure it would work, but maybe give it a try?

AW: [Nuke-users] "Referencing" or "Instancing" groups of nodes

[Thorsten Kaufmann]

Hi there,

i am aware of cloning, but you cannot clone groups. Also cloning has been an 
infinite source of agony here. Has this changed for 7? (Corrupt scripts
that can only be "fixed" by removing clones via texteditor). In addition there 
are python tools to create a linked copy as opposed to a clone, but that
also does not allow me to have a group of nodes being cloned. PreComp also 
won't work because I need the ops to be in the script and editable
live.

Thanks and Regards,
Thorsten

I believe cloned nodes does just what you are after? If you change the value of 
a clone it will also affect the "parent". Simply select and Alt+K.

I tried making a gizmo out a little network, but gizmos can't be cloned. At 
least not in 6.3.

Hey there,

i am trying to find the best way to "instance" (clone?) a set of nodes. 
Basically I want to have a bunch
of nodes that are then used at many different places within the script. When 
nodes are added/changed
it needs to be updated everywhere. In an ideal world it would work somewhat 
like a group that can be
cloned and expanded right within the script.

Any pointers or ideas? Please note I am also open to NDK solutions if anybody

Re: [Nuke-users] Re: extraneous samples in RAT deep image.

[Michael Garrett]

Thanks for checking in! It occurred to me that if you had a bunch of
overlapping hard surfaces that were possibly interesecting a little bit
(feathers?) then the extra deep samples are probably necessary. But if
you've got more of a deep holdout scenario where you have big gaps between
overlapping objects then the extra samples are probably unnecessary.

Re: the hider, we've checked it out but aren't currently getting the result
we expected. Lewis suggested dropping the opacity by a very tiny amount in
conjunction.

specially on primitives not facing camera. Tuning

compression setting effectively do it?

Do you mean the extra samples at glancing angles? I guess as you say if you
wanted to intersect something with those deep samples as there is a larger
z-offset between them by nature of angle pointing away from camera.  But
for hard surfaces with no intersections, it seems wasteful.

Re: compression methods, the factors appear to be:
- the z-bias setting (merge samples within a unit threshold)
- the subpixel samples, meaning, 3x3 creates a longer list of deep samples
per pixel than 2x2
- the deep compression which seems to be a global control for how many
samples to do.

Cheers,
Michael

Re: [Nuke-users] Trouble Importing my EXR with Layers

[Elias Ericsson Rydberg]

What I gather from your post is that you have rendered to multiple EXR's
instead of one EXR with layers. This is actually my prefered way of doing
it as a multichannel EXR requires you to shuffle out the layers anyway
(unless you want to specify what layers to merge in every merge node eg.)

If you are using V-Ray you pick exr (multichannel) as your output to get
multichannel exr.

My prefered way is to just drag and drop the folder containing the rendered
images into nuke, nuke will automatically identify the sequences and you
are good to go.

Re: [Nuke-users] Trouble Importing my EXR with Layers

[Steve Newbold]

I think he meant :S as in 'confused face'.

When you say rendered in 'layers' do you mean separate exr sequences per 
pass? How were you expecting Nuke to bring them in?  Each pass in a 
separate channel?  You either need to render into a single EXR from Maya 
or bring in the passes individually and shuffle to the correct layer set 
or create a script to do this automatically for you.

Re: [Nuke-users] Re: export camera and parent node from maya

[Elias Ericsson Rydberg]

I did a little script to do this, baking the camera in world space.

1. duplicate the camera.
2. put it in the scene root.
3. parent constrain it to the original camera.
4. for all attributes on duplicated camera connect attribute to the
corresponding attribute of the original. (to handle animated attributes
such as shutter angle or fov etc).
5. Bake the keys.
6. Save the duplicated camera out as fbx.
7. Delete the duplicated camera to clean up the scene.

Re: [Nuke-users] Noise patterns in Nuke

[Martin Constabe]

The noise node in Nuke is pretty effective. It has a Turbulent option in the 
type parameter.

Though there are hundreds of different noises to call upon, it is pretty rare 
that Fbm or turbulent don't do the trick. 

Even turbulence can be faked with two fbm noises placed over each other in 
difference mode.

Re: [Nuke-users] Noise patterns in Nuke

[Ron Ganbar]

Turbulent is just two fractal noise generators one on top of the other.
The Node Noise in Nuke is a fractal generator. Use two and play around with
them and you'll be able to reach anything.

Re: [Nuke-users] Re: Advice on angled shot - Actor inside of effect

[Ron Ganbar]

By the way, you can do this whole thing in Nuke.
Use either Nuke's particle system, or Geometry Tools and Dynamics plugin
suites.
See my blog about that:
http://ronganbar.wordpress.com/2012/11/13/nuke3dplugins/

Might make it easier to play around inside Nuke instead of back and forth
between a 3D package and Nuke.

Re: [Nuke-users] "Referencing" or "Instancing" groups of nodes

I believe cloned nodes does just what you are after? If you change the
value of a clone it will also affect the "parent". Simply select and Alt+K.

I tried making a gizmo out a little network, but gizmos can't be cloned. At
least not in 6.3.

Re: [Nuke-users] Amateur Question: Transform Node after Source Image

[Martin Constabe]

Your problem is caused by incompatible formats (e.g. HD vs . Cinemascope)

The great thing about Nuke is that it will accept any format at all. The 
downside is that this can cause workflow issues. 

Crop, Reformat, BlackOutside can all help.

Re: [Nuke-users] Amateur Question: Transform Node after Source Image

   1. Always transform after the key.
   2. If you turn on 'black outside' on the transform, you won't get the
   stretchy pixels.

[Nuke-users] Crop/Reformat in Place ?

[lewibaygo]

Hi 

i might have missed a step on this, but i doing a matte painting inside nuke at 
HD. Some of my elements used for the painting are also at HD

My question is how do i crop parts of the elements that i want, reformat them 
to  the new crop size and then over them back on top of a HD base plate for my 
matte painting into the same place without having to manually transform them 
back into place from the bottom left.?

The reason i ask is because i eventually want to skew some images with a corner 
pine so that they match the perpective of my scene like you would do in 
photoshop but i want the corner to be the size of the new reformatted element 
not the HD plate it was taken from.

Unless there is a way to transform and skew objects like you would in photoshop 
or even the roto/paint node using the same onscreen controls

if there isn't such a feature i hope there will be one soon  

thanks for your time

[Nuke-users] Advice on angled shot - Actor inside of effect

[Flares]

Hi, im relatively new to Nuke and am trying to create a shot, but im unsure of 
the best way to go about doing it, and was wondering if i could get some 
guidance.
The shot i have is of a person against a wall, from about a 30 degree angle, 
ive created an effect which has lots of small pieces for comping.
A video can probably explain better than me:
http://www.youtube.com/watch?v=_2smYVl0zrk#t=00m46s
Its at 46sec, while the pieces in my effect arnt glass, and are much bigger and 
fewer in number than in the video, the method needed will be similar i think.
The idea i have so far is to include some proxy geometry in my sim for my 
actor, for the objects to collide with. 
Then in Nuke roto out my actor - who luckly isnt moving as much as in the video 
i linked (no hair flailing about). Place the matte of the actor over the 
effect. Rotoing out the effect on her leftmost side, and having a second read 
for the part of the effect that will move infront of her - the part between her 
and the camera.
As i said im new to Nuke and so dont know if this is the best way to go about 
achieving this effect or if there is a better workflow, so any input or advice 
is appreciated. Thanks

[Nuke-users] export camera and parent node from maya

[NotDaBod]

I have a camera animated under a group node animated in maya 2013.

I wondering if I can bake the cameras animation with the group nodes animation 
onto the camera node for exporting?

Alembic and fbx don't like the hierarchy animation (the camera doesn't move 
properly in nuke).

I also tried using a parent constraint instead of parenting, and it still 
didn't seem to work.

Any ideas on how to export a camera animation for nuke with constraints or 
parenting?

Thanks

[Nuke-users] Re: extraneous samples in RAT deep image.

[symek]

Interesting conversation!
I always assumed those extra samples on solid surface help in deep compositing, 
specially near glazing angles where you really need the two z depth values per 
plate to make nice z-depth composite with other plates. Also numerically wise, 
different intersection values make sense, specially on primitives not facing 
camera. Tuning their number down seems like good optimization though. Doesn't 
lossy compression setting effectively do it?

[quote="Michael Garrett"
The other thing I want to do is render a deep image without dropping
hidden samples...that seems necessary to do a successful pgBokeh DOF
blur with deep images. We're still working on how to turn the "hider"
off in Mantra and get the output we need.

Appropriate option, Enable Hiding is on Render Tab of Mantra ROP:

Here's some info about the bug I sent to the Foundry.

For me this only happens with read nodes of MOVs in the script with postage 
stamp turned on.

If I try and copy immediately after opening the script Nuke freezes (even
copying text from the read node freezes Nuke up). 
If I leave it for about 20secs it's usually fine.
With postage stamp turned off it seems fine.

Is anyone experiencing this with image sequences? Our workaround for movs at 
the moment would be to disable Postage Stamp. Hope this helps.

[memetemin]

Hi,

I can offer some tricks.

First you need masked all moving object in your scene and identify this matte 
in camera tracker (You can do this camera tracker mask section and chect it by 
activate Tracking tab preview feature)

You should see in refine tab...you can refine decrease your max and track error 
slider after you should recalculate your solve.

And if there is a lens distortion on your scene you can undistort it before 
tracking, it might be help sometimes.

After track you can hover your mouse on points if its a good point its must be 
green and lots of stable frame (youll see numbers on it higest number is good) 
generally green is good red is rejected.

Best :D

hey falk,

that is at least super close to what I mean, ty! :)

I have a river mask and a specular pass of a sun. I gained the specular pass to 
a little point/middlepoint. Because of camera movement, the specular is moving 
and hits once in a while the riversurface.

The river mask drives the visibility of the specular dot, so either the dot is 
visible=white=1 when it hits the river mask, or it is black=0.

And these values drive the merge node where a flare is connected.

But I think what you posted is exactly what I need, just need to understand and 
rebuild it.

Big fan of your Tutorials. Great info.

Running parallel systems thing is really interesting. So it's basically having 
multiple OS and nukes running on your hardware kinda like how amazon has it's 
cloud rendering, sorry I'm never used it just read about it.

The SSD running 4k realtime is nuts. More processors then more Ghz is 
interesting too.

I'm looking into hiero as we speak.

Our production is 3d animation, no live action. We're going from Maya to Nuke 
and then FCP for final output. I'm not sure if heiro fits in there or not, I 
get the feeling that hiero is just for live action with fx?

Our comps using have exrs with lots of passes, also relighting is a must now 
and then 3d elements in nuke and particles. Is this a heavy comp?

If yes then more RAM and CPU's? 

SSD is always better I think but as fair as money and a budget seems like 
you're saying that SSD's will give then most bang on playing 4k etc?

Makes sense. SSD's help with the IO which might help for our EXR seq's maybe?

Cool.

[Nuke-users] Premult of Mask channel

[amstos]

While we ColorCorrect or Grade a CG render (with Alpha), which of the following 
method works best

Method 1:
-Create and connect 'Premult' node to the CG footage
-Create and connect 'Grade' node to the 'Premult' node
-Create and connect 'Unpremult' node to the 'Grade' node.
-Now when we adjust values on the 'Grade' node, it will also read the Alpha 
channel and we get to see nice edges while color correcting.

Method 2: 
-Create and connect 'Grade' node to the CG footage
-Also connect 'Mask' input from the 'Grade' node to CG footage (which will 
automatically read the Alpha channel from the CG footage while adjusting values 
on the 'Grade' node)

For me, both methods works good, just that 'Method 2' is simple with minimal 
nodes.

Does anybody has any work experience on both of the above and feel one is 
better than then other?

the title safe, the ones provided don't really conform to common standards as

[Nuke-users] Globally disable motion blur in the viewer?

[loocas]

Hi there,

just a quick question, is there a way to globally disable motion blur, 
everywhere in the comp tree for the current viewer?

I've seen this done in After Effects and it'd come in very handy as we use a 
ton of mblur all the time for shape animations, transform animations etc... so 
updating each frame takes progressively more time for the viewer to calculate 
than if I was to disable motion blur entirely.

But doing this by hand is impractical.

So, is there such a toggle or even a 3rd party tool for this?

Thanks a lot in advance, best

Hello,

I am wondering, if I can get numeric values from a luminance matte that I then 
could use to control for example the mix slider from a merge node.

Like white = 1 and black = 0.

Is that possible?

Thx.s

[Nuke-users] Having a really hard time tracking...

[seithr]

Hey all, im new to nuke and im trying to composite a robot spider (climbing 
down a wall) into a scene from band of brothers but im having a lot of trouble 
doing so. There scene i want to track is from 1:44 - 1:50 in this video

Problem no.1:
Im running NukeX 6.0v4 and it doesnt have the "refine" tab in the camera 
tracker. How do I go about filtering out bad points without this tab(ive seen 
tutorials where they drop the margin for error). I run a track in nuke and 
almost all the points are red or orange which is really bad... I masked out 
only the wall that I want to track as well. 

Problem no.2:
The scene is quite fast moving and jumpy and there is a few blurry movements of 
the camera when it moves fast making points impossible to see during some 
moments. 

Problem no.3:
Im using a 720p bluray rip and the video quality is OK but its definitely not 
the greatest. 

How would you guys recommend I get past these issues?

Thanks guys for the feedback.  Deke, I tried the unzip and that worked great.  

Now the million $ question... Is there any way to successfully run Nuke from 
the command terminal?  I'm trying to initiate a render job from a remote 
terminal, but I'm getting this error:

~/nuke$ ./Nuke7.0 
./Nuke7.0: error while loading shared libraries: libXcursor.so.1: cannot open 
shared object file: No such file or directory

I'm assuming that means I need to have an xwindows session going.  Is there any 
way around that?

[Nuke-users] "Referencing" or "Instancing" groups of nodes

[Thorsten Kaufmann]

Hey there,

i am trying to find the best way to "instance" (clone?) a set of nodes. 
Basically I want to have a bunch
of nodes that are then used at many different places within the script. When 
nodes are added/changed
it needs to be updated everywhere. In an ideal world it would work somewhat 
like a group that can be
cloned and expanded right within the script.

Any pointers or ideas? Please note I am also open to NDK solutions if anybody 
has done anything
Similar (e.g. would it be a feasible way to have a node that internally 
recreates a nodetree of
A specified group and acts like a clone?).

Kind regards,
Thorsten

[Nuke-users] Re: [Nuke-python] Pulldown_Knob with multiple checkboxes…?

[Howard Jones]

How are you intending to filter?

I built a script a while ago that gives you a drop down, this then is used to 
filter the next stage which is a list of episodes with check boxes, with multi 
selection allowed,
this then creates a panel populated with the shots found from the selected 
episodes. This way I could select a project/episode/and shots and add data to 
the shots (such as approved etc).

Would something like that be suitable

All done with the simple panel

RE: [Nuke-users] Particle rotation

[Gabriel Dinis]

hi Frank 
thank you very much for your time and attention to my question.
i kind of tried something similar as your way, just was using a card as a 
particle input, and a sphere as emitter.., but still i wondered id there would 
be a different way that we could manage downstream in the particle system in 
some another nodes (maybe), but i think this works for me..

thanks once again!!
Regards
Gabriel

it's a problem I stumbled into very quickly myself. It'd be very
nice for this to be added.

In the meantime, you can animate your input texture and randomly
offset that (haven't tested this properly though):



set cut_paste_input [stack 0]

resize none

}

Transform {

scale 0.69

  Hi Nukers.

i need help with something, i am kind of new working with nuke, 
now i am working with particles, my question is, if it is
possible in a particles scene, (particles are images), make them
rotate randomly?



thank you in advance, cheers
