MultiMatte and VrayBlendMtl

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
