I'll admit that the following screenshots don't depict the most attractive procedural world ever, but I think they're a step in the right direction. It's just proof that I'm able to build larger-scale works of proceduralism. I've been slowly building up the small, individual components for a long time, and I'm starting to get antsy to move on to the larger work (the combination of elements).
The scene uses the procedural texture generator that I've been working on. The generator is still not suitable for organic/natural textures, which is why the grass, mushroomy things, and sky all seem to have a metallic quality to them. Still, everything here is procedural, and that's the point.
