I’m rendering a scene and would like to use the multimatte pass on severel objects.
The problem is that this scene is very dark.
Somehow Vray don’t renders a clean multimatte pass in darker Areas.
In the attachment you can see a testscene.
On the left side you can see the multimatte when the only light in the scene is turned off or it’s intensity was set to a low value. Have a look at the edges where the objects are overlapping each other.
On the right side the VrayLight was turned on and the multimatte pass looks okay.
What am i doing wrong? Is there a solution for it?
of course i can render one time with the right light intensity and one time with a brighter scene get the right multimatte. But in the current job I’m rendering a animation with many frames and i don’t want to render the whole animation two times.
Is there a work around?
