Hi,

I mangaged it to project a picture on a wall. But if I put a mirror between the
"picture-source" and the wall, it doesn't reflect the projection to another
wall.

Is it possible to make this work?

Greetings,
  Tim

You have to use photons, but you need to ramp up the settings a lot if
you want the reflection to be sharp.

Thanks, for the tip, I will try it with photons.
