Hey guys So, I'm trying to use the TC curvature shader information of polygon models and I'm a little confused. If I apply the shaders in the example scene to my models the render comes out black, Im assuming this is because they are polygon models and all the example scene uses is nurbs. The site also claims there are…
I had to try with some example. Tile diffuse and grungemap from cgtextures. I modelled a highpoly source from the diffuse and used it for generating normals, ao and curvature. Spec as shown in image was created in photoshop with the curvature data and a grungemap.
