UE4 UV distortion and lightmaps overlapping

I've imported a scene into UE4 and I'm having some trouble with some UVs and lightmaps.

I've very carefully gone through and locked the positions of all the textures using "position tezture" in Sketchup or the "SketchupUV" plugin for complex meshes.

Most are fine, but I get a few (maybe around 30%) where the UV mapping becomes breaks and I get an error when I build the level in UE4 saying lightmaps are overlapping on certain objects.

I have UE4 generating a second UV channel for all the meshes to use as the lightmaps (shadows). ie: UV channel 0 = texture UV information, and UV channel 1 = lightmaps.

Any suggestions on how to fix this?

Possible future fix: automation with PlayUp to generate a second UV channel that will reliably reproduce the Sketchup UV texture mapping for game engine lightmap UVs.
