Hi!
I am currently rendering an outdoor setting with VRay Sun.
I need to split up the background and the characters.
Therefore I render the background elemnts and then the characters with all background objects set to be matte objects in their vray properties with these settings:
Matte objects: on
Alpha contribution: -1
Shadows: on
Affect alpha: on
Now I am getting strange colored GI on the background mattes when rendering the character.

The alpha of this imahge look like this.

When compositing the character on to the background in Fusion these GI colors look totally wrong.
It looks perfectly right when I "post-multiply" the character footage in Fusion, but this leads to the typical black edges around the character.
I don't wanna turn off receive GI on the matte objects, as this leads to pitch black shadows.
Is there a way to fix this without making a seperate shadow pass?
Thanks,
Flo
