I am trying to make a moss/snow type shader. this is the W.I.P
My problem is I don’t know how i can add a normal map to the moss.
The moss is y projected/blended onto the model using This technique
The moss y projection is blended onto the rock using the rock normal-map, this means i cant change the rock normal map without editing the the moss blending (which often leads to a broken shader).
My only idea is rendering 2 normal maps on the same model (Moss Nmap overlayed on rock Nmap) however i don’t want to do that because i don’t know how and it would be expensive.
Any ideas on how i can add A normal map to the moss?
