Vray GPU Cryptomatte

[Pixelpark]

Hi there.
I was experimenting with Vray Cryptomatte render elements (Vray 5 GPU, 3ds max).
At this moment it's not possible to generate the correct render element using the progressive image sampler, I must use the bucket sampler instead, right?
Unfortunately, this last is much slower than the progressive... Is there some development news about cryptomatte with progressive sampler?
Thanks

Cheers

Yes, that is correct, Bucket sampling is required for the Cryptomatte to function properly (this concerns CPU as well). We do have an improvement request logged for progressive cryptomatte rendering (internal bug-tracker id: VMAYA-7125). I'll bump its priority additionally.
