I'm don't use refraction here. It can give you good result by passing more lighting through leaves, but it TERRIBLE increase render time. It's ineresting to try but i think useless in commercial projects.

I have been using a small amount of refraction with a great result. I don't know if the high render time I get is from the refraction or because of the tree's geometry. Do you remember how long it took to parse the scene?

Render-time is about 3-4 hours in 1920x1080 (i7-3930) and about 50 passes.
