Yellow Square... Artefact ? Final Gather...
« on: September 03, 2015, 05:55:44 PM »
Hi, (sorry for the translation, I 'm French ... )  :D

I have a rendering problem as you see in the picture ... Large yellow squares appear when my " final gather " is enabled.

When I disable the " final gather ", the picture is much less realistic, but bug-free !

Thank you help me on this problem ...  :-\

First let me mention, that I'm not a mental ray expert, but most probably you'll need higher number of samples on those buckets.

I would suggest you a quick test using Forest Tools and export all scattered geometry to instances. You can find it under Utilities - More ... - Forest Tools. For more information about it, check our on-line reference guide. This way you can check that the problem happens during Forest object conversion or not.

Also, please feel free to send us the simplified scene (containing problematic Forest object(s)) through WeTransfer to to analyse it here. Thanks in advance.

Best regards,
