Vray Volume Grid

V-Ray V-Ray for 3ds Max Issues
1

Vray Volume Grid in GPU, not fully supported? When I tried putting a few of them together in this cloud case, the overlap gives weird result. CPU is fine.
The cloud is made in Houdini, exported the VDB to be used in max. The render preset is already using the fire/smoke from Houdini.

OK, I just googled for the supported features. Partial support for volumegrid, maybe Chaos devs are already aware of this then.

Hello,

Indeed this is something we’re aware of. It happens when you have a few intersecting Volume Grids and render them with V-Ray GPU.

I will update the thread when we have something on that.

Thank you,

Sweet, thanks! I’ll wait for the good news.

So hows looking?
I have a scene where I would like the grids to overlap.. is there a workaround?

Hey,

I’m afraid this is still in the to do list. Currently the workaround is to render it out using V-Ray CPU.

So I guess this will not make it into Vray 4… :frowning:

I’m having the same issue in Maya / Vray - intersecting Volume Grids don’t work properly on Vray GPU 4.3 - Can’t upgrade to Vray 5 either as this makes the scene too unstable :frowning:
