Hi,

I would be looking for information to render normal/positiveRGB/negativeRGB passes for volumes in karma (example for what i'm looking in attachment). Unfortunately here are any features like "Compute Normals for Volumes" in Mantra.

By exporting the volume gradient in a pass, I can almost get a result close to the "negativeRGB" but it's not crazy good and I don't understand how i can achieve the other results.

Has anyone ever successfully completed this technical application ?

I'm also providing my test file. https://we.tl/t-vAKroNptJT [we.tl]


Thanks !
