Hi folks,
I looked on the forum for a topic where it explains how to manage a multi matte with a blend shader but I didn’t found it.
Maybe one of you can help me out.
I am trying to make a matte pass for an element of my scene. It blends ceramic and golden paint through a mask.
The idea was to have a matte with both shader in order to edit them in post.
But I can’t obtain anything good.
here is my shader :

The green and blue circle are the two shader I want to have on my pass.
I add on them a Material ID attribute :

But it seems that the shader assigned overrides the Id of the matierials ID which interess me.
Is anybody have an idea ?
If I am not clear don’t hesitate to ask for further informations.
Thanks by advance
Cheers
