UDK Lightmap issues

[Torch]

Hey all, UDK n00b here. I tried importing an asset several times and building all but I seem to be getting shading errors. Its weird as I definitely have 2 UV sets unwrapped properly and exporting an FBX to UDK. Looks fine in the static mesh editor or when I place a light next to it in the scene, it only gets the errors when I hit build all. Any info would be appreciated!

As a test have you tried generating the lightmap inside udk through mesh>generate unique uv's dialogue?

Good point, I'm going to give that a try when I'm back from work and will update then, Thanks red

You might need to rebuild the lights in Unreal. This also happens to me especially if it is a new static mesh and I move the mesh within the editor window.
