UE4 Blend Materials Utilizing 2 UV Maps

hmm_rock

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!

Oh to answer my own question, maybe using a textcoord node with the coordinate index set to the specific uv map for that particular texture set? Im going to try it

For different blending options check this out. They are fairly easy to translate into shader nodes.

TexCoord with different index values sounds right to me for using different UV maps. But I don't work in UE4 that frequently to know it by heart.

Yes Rock, that is the correct answer.
