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!

That all make sense. If you ever got a workaround for this issue, please let me know.
Thank you for your quick answer.

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
