Path tracing

I've been playing around with Sunflow and I think I've got the hang of path GI now.

This one was a test of bouncing photons and meshlight's shadows. Smaller the light source, the sharper the shadows. As you can see, The big light on top, and the one in the middle on the wall, light up the bottom floor. This would be impossible withough indirect lighting.

For anyone who uses sunflow, I set bounces to 15 and samples to 30.

I also used gamma correction. It looked bad without it, you couldn't see the bottom. Heres the image before gamma correction [link]
