Using either Mantra or (ideally) Karma, is it possible to project light on a mirror surface and see the reflected light 'correctly' illuminate other objects? Stretch goal would be the same using gobo / projected image.
I'm trying to simulate shining a video projector on a curved mirror surface, and the resulting image as that light then hits other geometry.
You may need to turn on Caustics for this and increase Diffuse Limit to at least 1 In Karma CPU you can potentially also turn on. Guiding to help them resolve quicker
