| Sep 25, 2017 at 0:00 | comment | added | Secrop | I'll elaborate this answer later, but here's a solution I found while needing caustics, it's for refractions, but it works as well with reflections as soon you change the 'caustic' object material to glossy. blenderartists.org/forum/… | |

| Sep 23, 2017 at 8:26 | comment | added | Rich Sedman | Might be able to hack a solution using OSL on the surface (2) to trace paths towards the mirror and reflect them to the projector, summing over all valid paths. I don’t know how efficient (or not) it will be as it would need to trace many hundreds of rays off each surface point to resolve the whole projection but it should be quicker than relying on caustics. | |

| Sep 20, 2017 at 22:02 | comment | added | user1853 | read the first link. There are a few alternatives mentioned in it. | |
| Sep 20, 2017 at 21:57 | comment | added | Leo Ervin | I don't mind using a different renderer. Feel free to post an answer with using on.e | |
| Sep 20, 2017 at 21:53 | comment | added | user1853 | The reflections are not going to work unless you use a bidirectional path tracing engine like Luxrender. See: reflecting direct light on glossy surface in Cycles and How to create and animate the water reflection (Caustics) on an object? | |
| Sep 20, 2017 at 18:31 | comment | added | Duarte Farrajota Ramos♦ | See my answer here for the projection part blender.stackexchange.com/questions/57013/… Not sure how you can achieve the reflections though, Cycles is not very good at caustics. Also curious to see if anybody can come up with a solution | |
