Octane GPU-Based "Unbiased" Renderer

http://forums.cgsociety.org/showthread.php?f=59&t=841503

A new GPU-based "unbiased" renderer is now available. I say "unbiased" because it allows you to change things like trace depth, which is a little dubious for something supposedly unbiased. That said this looks rather impressive and the node-based approach is excellent.

Check it out.
