Is it possible to fake reflections per object in Cycles? If so, how? (I don't mean one image to appear as background and another to appear in all reflections). I mean using an image on the object mapped to reflection coordinates.
Scenario: I am using an Environment texture in the world shader settings. I have multiple objects each with reflective surfaces, one of which is using the Glass shader, I'd like the glass to reflect as it normally does with the addition of another image. To be able to blend the actual scene (objects+environment maps) with an entirely different environment reflection that isn't part of the scene.
