I have this sort of stone and I want it to have some lichens on the top but I want to control te quantity of lichens that is on the stone. Texture:
For that I've already this texture overlaping twice and I'm using the mapping node to control this. Result:
Using Python I'm trying to like simulate the aging and growth (more and bigger liquens) controlling the mapping node and my question is, is there any other way that this can be accomplished? Kind of controlling Uvs and adding this texture a few times?Image processing? Thank you.
