Bounce Light over Mirrors

[niravmadhvani]

a) How can I lead a projector-lights "video-beam" over many mirror objects to a wall. Without using a "fake" method, because I have to simulate a projection solution over a bended mirror

cascade.

You sound like you need the specular light portion of a ray. However, normal ray tracing only reflects diffuse properties. You'll probably want to look at the "caustics" in MR.

Although you say you don't want to fake it, have you looked into the SlideShow shader for lights. This lets a light course cast rays through a texture, such as a "slide show".

Sorry I can't help more,
