I'm trying to make an infinity mirror in blender. I've managed to make a two way mirror by using the back facing geometry input to apply two different materials to either side of a face. Everything works OK but I only get 6 layers of bounce between the two mirrored layers before it stops.

How can I turn the number of bounces up to infinity so that the light pattern continues on indefinitely or until it fades to black?

Thanks. Here is an example rendering:

Limited bounces

  • $\begingroup$ Try a really high number of bounces, like 100,000? $\endgroup$
