i am having some serious rendering problems with a farily simple scene and materials, this black squares appear randomly and change each frame. It would sound like a bug becasue sometimes the same frame renders cleanly from an other machine or after reeboot, I checked everything i could think about but no improvement. The only thing that seemed to be working, but only in Mplay renders,wes the rising of Raytracing bias, Z importance and Shading Qiality Multiplier. It was initially happening only in one file, but now is on two different scenes which share most of th esame assets and i don't know where to go. I would share a scenefile but there is a lot of stuff attached to it. Any help or suggestion will be very much appreciated since is the last week of our master project!
also it resembles artifacting you'd get if you are using Displacements and your displacement bound is not high enough hard to track down without a scene
