This is kind of confusing but hopefully I can explain it clearly.
I have a scene with moving objects and moving lights, that also has a mirror (using a phong shader) in it. I want to render the scene, but have the geometry that is reflected in the mirror to have different textures in the reflection. so for example, a checkered yellow sphere will pass by the mirror and look like a blue sphere in the mirror reflection.
So far the only idea i have is to render the animation twice, once normal. and then to change the textures/shaders/lights and render it again, and them compositing the 2 layers with a mask.
But is there a better way to do this? i am guessing setting up some kind of render layers might help? maybe one just for the reflection? one thing I am concerned about if I just mask it out like i am thinking is when objects move infront of the mirror, do i need to composit with depth information??
Any pointers would be really apprecaited! Thank you anyone who is willing to help!
