Final gathering. Took about 20 minutes to render. 16-64 samples, 20 MC samples with 2 bounces max, 1 million photons. I didnt do anything fancy with the caustics map or anything.

Only indirect photons stored in the map. Same parameters as before. Took 1.5 minutes to render.

Both direct and indirect photons stored in the photon map. 1 million photons, 4 bounces maximum. Took about 2 minutes to render.

Tried doing normal direct illumination, but with photon mapping for indirect illumination, but it looks really bad...
