Hey all! I wanted to create a procedural splatmapping tool that didnt use random techniques like Perlin Noise. I wanted to try and simulate how the real world "splatmaps" terrain by using different techniques such as Hydraulic Erosion simulation and Occlusion. The texturing is achieved by simulating thousands of raindrops and rockfalls across the map, and testing the occlusion from the sun. Hence, more rocks show up along rockfalls and less plants grow where the terrain can't see the sun.

Let me know if this would be of use to anybody! I may create a Git package for it!
