ZDepth/Maya fluids

[obrad1972]

Hi

We are rendering clouds using maya fluids (VRay 3.1) and clouds are appearing black in ZDepth channel everything else is correct.

Anyone knows how to fix this issue ?

Thank you
Obrad

It's not currently possible. V-Ray doesn't support z-pass for volumetrics. VRayVolumeGrid supports this via a sperate channel, but it doesn't work with Maya fluids currently.

Thank you very much Ivaylo.

Do you know when this will be possible or if is any solution to exclude fluids from ZDepth pass?

[ivaylo.ivanov]

Not sure if we will have time for the next SP. It's possible to do this even now using a little bit of scripting though. Enter this into the Render Settings -> Post translate python script

from vray.utils import *
fluids = findByType("PhxShaderSim")
for f in fluids:
	f.set("volzdepth", 1)

If you set 2 instead of 1, you will get a separate z-depth channel only for the fluids.

When the next SP will be ready? I can see lots of speed improvements in Max version (sp3) ?
