Maya Vray Clipper and Vray dirt issue

[cum. m+d]

Hi guys i have a problem that I've been facing with Vray clipper and vray dirt. When I tried to render my scene with the vray clipper, It looks fine in the beauty pass. However in my vray dirt pass, I got some unwanted shadows on objects that are excluded from the vray clipper.

I did a simple test setup, by using vray clipper-mesh mode, to clip cube A.
In my clipper settings I excluded cube B. however in my vray dirt render, the surfaces of the cubes inside the mesh clipper gets rendered out black. Cube B, which should be excluded by the clipper got affected as well. Not sure if this is a known limitation with regards to vray clipper and vray dirt. Wondering if anybody had a solution to this problem? Been going around looking for solutions but I couldn't really find any. ><

Another thing I discovered is that when I'm not using the vray clipper mesh mode, the vray dirt render of the clipped surfaces turns out fine. You also get this weird shadowing on the objects that are being excluded in the clipper list ().

Im using Maya 2016 Extension 2, vray ver. 3.4
In my setup I'm only using a vray domelight, with no GI.



Any help appreciated!! Thank you!!! 

This is a known issue which is not resolved yet, avoid using the V-Ray Clipper with V-Ray Dirt for now.
