[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [56478] trunk/blender/intern/cycles/kernel /closure/bsdf_microfacet.h: Fix #35160: cycles was rendering glossy BSDF' s with zero roughness too rough

[Thomas Dinges]

Hi Brecht,
after this commit, color_ramp.blend (from the regression tests) renders 
quite differently.

5 of the 6 spheres in that scene have a roughness of 0.0. (Glossy or 
Glass shader)

2.67 RC: http://www.pasteall.org/pic/50540
Trunk: http://www.pasteall.org/pic/50541

Best regards,
Thomas
