I got some benchmarks from my cg guys on CPU, GPU, Hybrid. But the Hybrid seems to show some areas semi rendered or unrendered. Anyone have any idea how it happens?? We are on hotfix2 of vrayNext on MAYA

I can reproduce this, although rather randomly here and have logged it in the bug tracker (ref id is VGPU-3896).
We’ll post here when we have an update.

I have reported the same types of things and I believe Vlado is also looking into it also.
