I can’t figure out how to use T_Fire, T_Flow, and T_Lightwrap.
More specifically, what is supposed to be plugged into the "position" pipe of the T_Fire, how do you get the T_Flow working, and I’m assuming an alpha needs to be plugged into the T_Lightwrap, but it’s unclear where and how?
Anyone use these?
pick color you want to suppress (red, green, blue)
pick the spill method (min, avg, max…avg works best in most cases btw)
then tweak the spill amount
Enjoy!
I’ve got the dropdown menu in my group now, but now i need to link it to the switch node with an expression.
Could anyone help me out with the proper expression and where to put it?
Thanks,
Tom
now what Im thinking is that let me write one py script where i can call alot of py scripts from my server where I can put all my py scripts globally… can i know how is this possible?
another question would be I would like to use system env variables in nuke like COMPUTERNAME, USER or some specific File directory variables rather than redefining them in Nuke again using py or tcl I would like to use the system variable straight ahead.. But they are not working… how can I do this? do i need to generate the py script and load it at the time of startup?
can u guys pls help me..
I would love to be able to change colors from my maya renders in post using label/object id passes with everything embedded in an exr.
But I have run into problems…
1.I understand that this is a maya question but I can’t find any simple ways of getting my label/object id/coverage passes out from mayas framebuffer. Do I have to assign an mi_label to every object in my scene manually like Chapter III on http://www.sigillarium.com/blog/lang/en/379/#III ?

They mention that you could use the Diffuse Material Color pass for masking if you’re just using straight colors, is anyone using this approach?
2.If I do get those passes out (hopefully with some help from some of you) I understand that the label pass will be without aa, now I have been searching quite a lot and found a thread where Hugo had written a macro to get hold of the id’s and then apply some fake aa but it seems that the gizmo is broken in newer versions of nuke.
Therefore I’m requesting a straight out nodal workflow (no gizmos) that helps me getting those id’s as an alpha channel.
I can easily do this with a shuffle node when it comes to r g or b, but how can I get hold of custom colors to use as a matte?
3.What are coverage passes for? I figured they were used to make aa work correctly with non-aa passes hence skipping the need for Hugos fake aa controls in the gizmo. If not… what can one use them for in post?
4.Is anyone using this workflow successfully or will there always be problems when changing an objects color afterwards? My ideal situation would be to be able to do color variants of products I’m rendering without having to re-render everything for each color version.
Thank you very much in advance, hope some of you can shed some light on this.
In shake you can use the reorder node to set the node to luminance (by setting it to llll).
In nuke the shuffle node doesn’t allow to do this, does it?
And with the math node, if i put r=l g=l b=l, i’m not getting the desired results.
Anyone got any ideas?
Thanks,
Tom
Nuke will run under Windows 7 ultimate?
I cant find info about that.
Thanks in advance.
