Hi,

As in the previous post (1. photorealistic play-doh 2. round off at csg
edges) I am trying to create a photorealistic clay surface. In addition to
the bozo normal pattern which gives the clay a smooth moulded look, I want
to add some cracks here and there. I guess something can be done with
layered textures:
texture {MouldedLook}
texture {AddedCracks}
but every time I end up influencing the MouldedLook texture also at places
where there's no crack. Can someone help me on:

1. how to simulate a normal with random cracks here and there (so preferably
without a bump_map)
2. how to declare the texture in such a way that it doesn't mess with the
underlaying MouldedLook texture at places where there's no crack?
