I worked through Andres Rodriguez’ tutorial on creating a ground material, but in Blender instead of Substance Designer. There weren’t any problems really and I’m quite happy with the result. Lots of variations can be made. The advantage of using Blender is that the final output is not tiled but uses the infinite noise/fractal algorithms which look a lot better than tiled images on a larger surface.
Here I’ve added some Purple Lovegrass from Andrew Price’s Grass Essentials collection, so the gound is not so obvious but at least is not obviously bad.
