Light Cache on GPU?... doesn't seem like it.

[jknott]

I'm rendering a sequence in 5.1 and watching my CPU/GPU usage. During the build of the light cache my CPU is at 100% and GPU is at 0%. What's up? I thought it had moved to the GPU. I've tried CUDA and RTX modes. I have both a 1080ti and a 2080ti in this machine. I'm not seeing much in the docs about this. Am I missing something?

Have you ticked the "GPU Light Cache (WIP)" checkbox?

[jknott]

I did not! Didn't realize it was optional and I was looking in the 'Light Cache' rollup, not the 'GI' rollup. Thank you. First tests are significantly faster

Hey Aleksandar, can you please tell me where this checkbox is, can't seem to find it in the render settings.
It seems that GPU isn't using light cache in my render. Same goes for the Bruteforce GI.

The option is located in the V-Ray tab under the GI rollout of the V-Ray GPU render settings (see attached screencap).

I'm very curious to see the option at VfR too.

Thank you Aleksandar!
Looks like Maya Vray version is a step behind 3dsmax version.
