(Fixed) [HOU-2330] Pyro bake volume

[ghiom3d]

HEllo, how to make pyry bake voilume working with Vray ?

I have setup it like this.

i load a vdb and add pyro bake volume node
on this node i change :
i assign my volume vray material in assign material
on scatter a say none to downsample
in bindings i check baked emmission wich create a Ce field for emmision.

So, i have 2 new fields to play with.
Scatter and Ce.

In my volume vray material, in field i try Ce or scatter to make fire but nothing happen even i put something like 10000 in fire multiplier.

when i check with geometry spreadshit i saw 0 everywhere for scatter and Ce.
Seems empty ? but it's work with mantra if i use the mantra shader.. even there are all 0.
And of course in viewport it's not 0 at all we see fire in smoke.

any idea ?

Looks like fire is broken in Vray 5 shader.

Hey ghiom3d ,

Yes, a V-Ray Core update with some default settings changes has caused the export of one of the parameters to be incorrect. We've already fixed this internally and will try to update the builds as well.
You can use the following Renderer ROP -> Post-Translate script to force the export:

import vray
with vray.VRayRenderer() as v:
    for p in v.plugins:
        if p.getType()=='PhxShaderSim':
            p.earg=1 

Best regards!
