Vray Dirt urgent help needed

V-Ray for 3ds Max V-Ray for 3ds Max :: Issues
1

In the Vray manual it says that excluded objects in Vray dirt always render out in unoccluded Color, which is in my case pure white. But it always renders out pure Black.

I use Vray dirt as an AO pass in Vray Extra Tex and i need the Excluded surface to be rendered in white since its a glowing surface that should not be affected by AO when multiplying in post.

I really need help on this since i have a tight deadline to solve this problem.

Best regards

Björn

without going into detail about your ao setup what I may suggest is if you have a multimatte element for the glowing object you can just remove the ao from that object using that id channel making it white in post.
