Jagged Arnold shading regardless of Arnold render settings


#1

Hello

It’s my first posting here and I’m in desperate need of help with a buggy Arnold rendering problem, which could not be solved on the Autodesk Maya Shading forum. I cannot upload attachments yet as a new user, so I’m trying to define the problem in words as clearly as I can:

The problem encountered is no matter which AA, SSS and light intensity value I set, the boundary between light and dark appears jagged.

Concerning the lighting system, I have a primary area light in front of and to the left of the object of focus, sub area light in front of and to the left of the object and the back area light behind it. Moving these area light objects around didn’t change the shading edge either.

It would be appreciate if anyone could help me make the shading edge smoother.

Thank you in advance.
