Cycles: Fix excessive sampling weight of glossy Principled BSDF components If there was any specularity in the Principled BSDF, it would get a sampling weight of one regardless of its actual impact. This commit makes Cycles estimate the contribution of the component and adjust the weighting accordingly, which greatly improves the noise characteristics of the Principled BSDF in many cases. Note that this commit might slightly change the brightness of areas when using MultiGGX and high roughnesses, but the new brightness is more accurate and closer to the result of Branched Path Tracing. See T51836 for details. Differential Revision: https://developer.blender.org/D2677 |
