Hello,
Attached are two pictures of a mostly reflective chrome ball also with a displacement map, reflecting a vray dome light.
Almost every frame in the sequence get the artifact with the dark triangular pattern. This pattern changes wildly for each frame.
I also got this error with a different render where the object had No displacement map at all.
Does anyone recognize and can tell me what it is and how to get rid of it?
cheers
fred
a wild guess but it may be your scene scale or camera clipping planes? Also have you tried turning up raybias?
Have you checked for overlapping geometry?
Best regards,
Vlado
Thanks for your suggestions.
I slightly upped the ‘Secondary ray bias’ and that seems to change things in the right direction.
But now I have the problem that the render comes out completely differently whan I render to maya’s render window and when I do a maya ‘Batch’ render. Using the same maya scene file.
Take a look at the attached pics.
(Ignore the slight colour difference, thats just different viewers.)
Has anyone else bumped into this phenomenon?
cheers
fred
