My first underwater scene, in cycles.
Halo done with volume scatter, caustic with ocean modifier.
Only 200 scan but it took 2 days to render!!!!
Blender 2.70, cycle, gimp 2.8, Sand material was done by Szyko taken on blendswap, thank to him (CC-BY-NC licence, so this image can't be use for commercial use and you have to cited the author).
