I want to place a moss decal on a rock. But, I want it to project moss in a certain shape only. Lets say I want to have moss on the rock only in circle pattern like image I added with the question. Is there a way to do so, like adding an alpha map that will determine the shape of decal spawn point?
For some reason I did not think deffered decals were the answer, but it turns out they are. I learned how to set up the material to have this effect in the meantime!
