BDPathTracer Bug with Falloff in the reflection slot

[anchovy]

Stumbled upon this one. Not sure if its a bug or as designed. It appears the BDPathtracer doesnt like a falloff using light/shadow in the reflection slot of the VrayMtl. Im also seeing the material not showing up two sided if it used the full Vrayblendmtl.

Here is the Scene using the ProgressivePathTracer.



Here it is the same file using the BDPathTracer

The shadow/light falloff type doesn't work very well even in the regular V-Ray when GI is enabled. It won't work with the bidirectional path tracer for sure, since this falloff type is not physically accurate.
