replaying okami

So I decided to finally try beating Okami, I ran out of steam last time. I think I figured out a big chunk of the fancy cel-shading technique they used: I think there's a lower-poly model around each object with inward-pointing normals, and a shader on those polys that contributes to the ink-filter. This is pretty clearly what's going on on most of the landscape, and SOME of the characters. I'm so smart.
