Sergey Sharybin 3f5771475d Cycles: Don't perform re-intersection if ray distance is zero ... It is possible that ray distance will be zero which would make intersection refinement return NaN as the refined position which would later lead to all sort of mathematical issues. Don't think there are ways to improve intersection accuracy for such rays so just return original intersection coordinate. This should fix T43475. TODO: Need to look into possible issues in Ashikhmin BSDF which might return zero-length reflected/transmitted ray?		2015-01-31 01:49:48 +05:00
