Hello,
I would love to be able to change the volumevisualmode intrinsic of a VDB.
It can be changed on a Houdini volume but as soon as the volume is converted to VDB, the attribute become read-only, sadly.
Thanks!

Hello,
I got a mismatch from Houdini render view and Nuke when the background image is enable in Houdini.
The smoke look correctly comped if I disable the OCIO or if I turn off the ‘Toggle Transparency’.
The value of the smoke are over 10 and the alpha is around 0.7. I would expect a final value of 7 over BG but I got value around 0.4 instead. (BG value are pretty low {0.03, 0.02, 0.02})
I'm a bit confuse on how Houdini compose the render over a background image.
It seem different from Nuke ‘over’ (A+B(1-a))
Thanks for your help,
Gabriel

Hello!
I can't find a way to put an expression that link a color ramp to another one in python. (like a copy / paste relative references would do)
I know it's kind of a hidden multiparms, but I can't correctly put an expression to each of these parms.
The setExpression is kinda linking the parms but this don't seem to work because when I create a new entry in the ref(new color), it's not linked.
