The Random by Poly sampler info option is not yet supported on the GPU. We already have an improvement request logged (internal bug tracker id: VGPU-3618 ) for its support. I’ll bump it additionally.
I’ve also logged an improvement request (internal bug-tracker id: VMAYA-9947) for the Random by UV Shell.
Has this been addressed ? Seems to still be a problem with vray 5, quite a big limitation for GPU workflows. Is there some workaround for this in the meantime ?
