Diffuse falloff error when using GI and directional-light in V-Ray for Maya. #4

Closed petermcevoy closed 7 years ago

petermcevoy commented 7 years ago

The falloff of the diffuse component looks off when GI is enabled and a directional light is used.

The error appears to be most noticeable with the Maya lights (directional, sphere, point, etc) as opposed to the Vray Lights. I also observe that the error is only present if GI is on. The GI part confuses me frankly, but the affect of turning it off completely eliminates the error. Tested on Vray 3.5.01, 3.5.02, 3.5.03, and the nightlies for 3.6.
