(Fixed, Fixed) [HOU-1920] [HOU-1923] volume GI properties

[psanitra]

I was looking into using volume GI properties on OBJ spare tab to boost volume GI, and get away tracing less bounces( 4 instead of 8 for example) . But it seems this setting have no effect on the render result. Is it broken or i`m missing something? If that`s just for matte state, where is the "normal" GI multiplier?

Hey Peter,

I spent half a day yesterday trying to figure out what's going on, and finally noticed the error message in the console...
This should be a simple fix on our end but in case you'd like a workaround until then, you could put the following in the Post-Translate tab of the Renderer:

import vray
from vfh import vfh_utils
renderer = vray.VRayRenderer()

for p in renderer.plugins:
if p.getType() == 'PhxShaderSim':
p.generate_gi = 1
p.receive_gi = 1
p.gen_gi_mult = 1
p.rec_gi_mult = 5
p.generate_caust = 1
p.receive_caust = 1
p.caust_mult = 1

Glad you found it! Will try this for now. Can you please notify me when the build with the fix is up in the nightlies?

Thank you!

Hey!

Today's nightly builds contain the fix for this. We added those options on the Volume Grid Shader itself, and also kept them on the V-Ray Object Properties in case that is more convenient. The latter will override the options on the shader.

The issue was with the parameter names so it's necessary to remove the old object properties and re-assign new ones if you go that route.

Best regards!
