aleks - my experience with mirrors is they can have different lighting than the environment they reflect. Now are these truly mirrors or portal renderings? If its a portal rendering you won't get exactly a mirror. Portals are used in game engines. Basically the camera is placed at the portal, the scene is rendered from that viewpoint then the resulting render is placed as a texture on the portal geometry. Somewhat similar to p4 shadow maps where a render is done at the light position to get a shadow mask. I'm curious to see the actually materials setting dialog. I'm wondering if they allow us to set smooth shading on or off for materials so we don't have to break verticies to get flat surfaces.
