Model import with strange UV set
OK, so this is a special case. I modeled this one with 3dsMax 2014, create 2nd UVs channel, as you can see in this file. However, when I export them with .fbx (2014) format, the model only has one UVs set, and that UVs set comes from nowhere, it doesn't match with any of model's UVs set.
I got this problem not only with UE 4.12, but also with every UE version, since UE 4.8.
Is this a bug? I don't think I did something wrong. Everything else in the scene is fine. This is the only one cause me trouble.

You actually have 4 UV channels applied to the staircase. Unreal seems to be only reading the last two. I noticed that this usually happens if you import a model from another program (Like SketchUp) that has already been UV mapped. The only way I know that consistently fixes this issue is the following steps:
Let me know if that helps,
