Any Refraction IOR value except 1.0 creates black artifacts #26

Tested with RadeonProRenderSDK 2.02.2, also reproducible in the Blender addon image

Using any refraction IOR value except 1.0 creates these black rendering artifacts appearing within the object.

Here's an example made in Blender 2.91 IOR bug Blender.zip

Did you try setting RPR_CONTEXT_MAX_RECURSION to e.g. 10?

jrz371 commented 2 years ago

Yes, we use 8 as a default and even at 10 there is no discernable difference.
