I’m getting infinitely frustrated with this problem, I create a UV map for my material layout in 3DS and assign it to Mapping layer 1 in 3DS, no problem.
I then create a second set of UV’s with another UVUnwrap modifier in 3DS, and unwrap that for the lightmap, again, no problem.
The problem is, when I import the mesh into UE4, it only imports the top-most layer of UV’s as channel 0, and ignores the others completely. I can’t seem to import both UV channels at once, any ideas why that is? Getting infinitely frustrated with this now and there doesn’t seem to be any fix. Using UE 4.0.2.
What’s odd is, all the other models I’ve made this way have been working fine!
