I´m just working on a project that requires some matte painting work to add backgrounds to the scenes.The matte should consist of 2 or 3 different layers that i paint in photoshop and map to geometry using maya.
so my questions are, what is a common shader setup here, i experimented using surface shaders with mapped "out color" and a mapped "out matte opacity", but I still get some black spilling when i render this out.
what is the technique in Photoshop to get the correct alpha channels to avoid this spilling?
is it right to render out the mattes in a 3d app once again, and what renderer would be used in maya?
im very happy for any help, shots must be ready very soon!haha
