This is a procedural shell generator I made recently. I was inspired by one of those videos of snails eating cucumbers, and I was gonna make a 3D sculpt of a snail and ended up being so interested in the way the shells look that i never got around to it. Both the geometry and the texture are procedural.
Above you can see a number of shells generated with my tool. Note how wide the variety of results you can achieve is! All of them have been retopoligized using a highly automated workflow and baked to a single atlas texture.
Above you can see the usage of the generator. Note how easy it is to customize the shell, how easily they are retopologized by 3D Coat’s autopo, and how nice the result is.
Take a look in the 3D viewer!
