Description Adam Goodenough 2016-02-08 13:48:52 EST
When running a combination of SRS and a Lambertian surface, odd artifacts appear which end up being reflections of the surrounding area.
Comment 1 Adam Goodenough 2016-02-08 13:51:10 EST
This was tracked down to a previous fix for BRDFs which had specular lobes with values
smaller than the average reflectance and a couple of errors in the checks based on differences in min/max specular reflectance. These errors have been fixed (4.7.1) and the artifacts are no longer seen in test images.
