Vray dirt viewport

Hello, is anyone getting the vray dirt map showing black in the viewport Vray 3.40 Maya 2016 Ext2 SP1 windows 7?
The render comes off fine but working with a black object in the viewport is not ideal.
I’ve got dual Titan X drivers up to date and this issue is not happening in Maya 2016 viewport Vray 3.30.
Any ideas Chaos?
Other than that , great job on the new viewport 2.0 , the textures finally show up beautifully.
Thank you.

could you attach the scene, you can replace the buildings with boxes.

Thanks Zdravko..here’s a scene.

Thank you for the scene. I reproduced the issue and forwarded it to the developers. As soon as I get any update from them I will let you know.

Lovely, Thanks again.
