[Bf-cycles] Render passes and flat mirrors

Hey Adriano, everyone,

You would have to create these custom passes as render layers instead, or
perhaps in a different scene completely. Either way, you would basically
create a material for the pass you want (using camera depth, AO shaders,
solid color emission shaders for IDs...) and assign it to everything, then
assign a normal glossy shader for the reflective mirrors.

On a related note, one thing I like in Maya (although it's also the most
buggy thing I've ever worked with) is the ability to override materials per
render-layer, meaning an object can have one material assigned to it for
one layer, and a different one assigned to it for another layer. Is this
possible in blender currently without duplicating the object or scene?
If not, is it a feasible idea? It could even be node based, using something
like the Attribute node as a sort of boolean "Is X Render Layer", like
mask/matte type of thing.
