UE4 Material node setup

Johola

Hi Everyone, I have an asset created in 3DSMax imported into UE4 that uses 8 materials through the multi/sub-object material assigned in Max. Each material has the following maps: Normal, Albedo, Roughness, Metallic, and Ambient Occlusion. What I needed to know is, if it’s possible to setup a material in UE4 that can combine some of those materials together reducing my original 8 materials to 5 or less? I would need this setup to be able know which normal maps go with what particular section of my asset. I’m trying to avoid unwrapping some sections again and combining them in 3DSMax in the same 0-1 grid as it will affect the resolution of some of the combined sections. I hope I’m explaining this correctly.

If I understand you corretly, what you can do is create a shader driven by an ID map as a mask per element (4 IDs per map [R,G,B,A])
