I want to use two normal maps for my mesh since one is related to the material itself and the other is related to the mesh. I tried to achieve this with a detailmap but I realized that this won’t work. I don’t need diffuse and roughness of the detailmap so red and blue channel are wasted and the green channel isn’t enough for my normal map.
So my question is how to use two different normal maps for the same material. One normal map should point to uv map 1 and the other normal map should point to uv map 2. Do I have to create a node material or is there another way? If yes, how to create the node material? It should be 100% the same like the regular pbr material but with the opportunity to add a second normal map.
I appreciate your help.
