Hi all, I am working on a large site and I have mapped an aerial photo across the whole ground surface as my base texture. It looks great but feels flat and I want to add some grass bump/normal detail on top of it.
The problem is that when I try to add a normal map, the UV tiling controls affect both the aerial photo and the normal map at the same time. My aerial photo needs to stretch across the whole site once, but the normal map needs to tile many times to look right.
Does anyone know the best way to keep the big photo as the normal map while using a different-scale normal map?
Thanks
