VRay2Sided alpha - bug or feature?

[Oleg_Budeanu]

So I am working with VRay 2-sided material and noticed, that you should use an alpha map in both of the materials - front and back. For me it does not quite make sense as if the front material has an opacity map - it should work on both front and back side, right? I mean maybe there is sense to make a separate field in 2-sided material for opacity map, which will be used for both front and back materials. Correct me if I am wrong.

This part of V-Ray needs to be reworked in general, but you are correct that having a separate opacity slot in the 2-sided material itself probably makes more sense.
