I am interested in potentially creating new materials for the surface of kerbin using substance designer. From what i have found from looking around, the go to way to adjust planet properties is to use kopernicus, but exactly how to go about changing planet materials is unclear. I am looking to create materials using the unity standard shader and then replacing the closeup tiling textures (grass, cliff etc) with them. However, it looks like custom shaders are quite code heavy to get working so im not sure how to go about this idea. Any ideas about how to use custom materials for terrain would be much appreciated.
just as an example here is an image of a potential cliff material i created.
