Cycles Principled BSDF violating energy conservation?

WebA Bidirectional Reflectance Distribution Function (BRDF) is a function that describes the reflectance of a surface. There are several different BRDF models/algorithms, many of which are not physically based algorithms. For a BRDF to be considered physically based, it must be energy conserving. Energy Conservation states that the total amount of ... WebApr 3, 2024 · Go to file. Brent Burley Fix disney.brdf bug. Don't pass int literals to mix.
