multimatte reflection ?

Hello !

I have a scene of a conference centre where one side of the room is made out of mirrors.
The client want to see different seat colors simulations, so i thought doing a multimatte on the seats material and then just photoshop it fastly.

But, is there a way to have the multimatte work in the mirror’s reflection ?

thanks !

Not at the moment, you will have to render a separate pass for the reflection mask.

How do i do that ?

you would assign simple vray light materials to the geometry of your seats with various colors (green, red, blue), then have those seats not visible to the camera, and only render mirrors in a black environment, so the only thing the mirrors will reflect would be the colors of the seats.

Ok thanks !
