    Be sure to check the lightmap UVs (index 1) inside UE4. If they don't look like they do in the Modeler, then go to each LOD of the mesh and disable the "generate lightmap UVs" option and click apply.

    That is a new feature in UE4 that unfortunately stomps the lightmap UVs you can edit from within the Modeler. It has already been fixed so that imported SpeedTrees will have that off by default. That fix will be available in the next release of UE4, but for now you may need to disable it manually in the editor.
