I saw that one of rock materials in one of downloadable unreal projects was a black rock with moss on top. …no matter how i rotated or morphed model moss would ALWAYS be on top. I’d like to learn how to achieve for I’m sure it would teach me a lot of things.
Can someone explain to me how that’s done?? or point me in a good direction at least?
I’ve not seen that material myself but I assume they were blending between a moss texture/normal map and a rock one based on dot product between world space normal and (0,0,1).
