Brazil 2.0 for Rhino SR3 Beta 4 is now available from:
There's only a couple of new things in this release - but importantly, we've written a Curvature shader - one of the items on the wishlist on this forum. The shader blends between three colors/textures - concave, flat and convex. You should be able to use it in combination with Occlusion to better model dirt effects.

Thanks Andy! The curvature shader is much appreciated! :) One question though - Any chance of blurring the edges using a custom curve or just a simple value?... Also the "Self" option seems to still not work. Are we still waiting for Rhino to issue an SR? I noticed there is an RC of SR1 available now... jonah
Actually, that's pretty difficult. Of course, you could always blend those corners instead of filetting them - the reason you have abrupt changes in shading is because you have abrupt changes in curvature.
