UVW Channels?

  1. Can Unreal use multiple UVW map channels?
  2. Are they also being exported with .fbx?
  3. Or do you have to use .datasmith?

Thanks for any little help!

Yes, you can change the UV channel with a TextureCoordinate node by plugging that into the UV input of a texture in your material. FBX supports multiple UV channels, .obj does not
This doesn’t require Datasmith, it works for all imported FBX files
