Does anyone know if there is a way to blend/overlay a detail normal map over another in UE4? For example, you have a plain marble wall (UV1) and want to add detailed normal information along the trim (UV2).
The closest info I could find was https://forums.unrealengine.com/showthread.php?45063-Multiple-Normal-Maps-on-Separate-UV-Channels
(which seems to have issues of its own) but I'm unsure what nodes to use to specify that the detail texture should be mapped to UV2
Any help appreciated!
