Using a reflection plane on top of a material with very small or 0 roughness will give you a nice result. Just make sure you place your reflection plane a few cm higher than your object.

Vasilis,

I've followed your instructions here and been able to make a mirror surface, but I don't see any of my lighting beams being *reflected* by the surface?  Like I can see the mirror image of what is happening in front of my Reflection Plane, but nothing is actually being reflected which is the main effect I'm looking for.

Do you know how to accomplish this?

Thanks!

At the moment, mirroring in Capture is limited to image reflections. Light beam reflections (bounces) are not yet supported.
