Just set which UV set must be used in UE4 for lightmaps
When you import a mesh to UE4 by default it has an import setting that will generate an additional UV channel for lightmaps and set that as the default for the lightmaps. If you already have your UV’s the way you want them, then uncheck the Generate Lightmap UV’s option when you import. If that’s unchecked then it will assume that the first UV channel is for your material and the second UV channel is for your lightmap.
If you reimport something that you’ve adjusted, you will need to open the Static Mesh and change the lightmap UV channel to be the correct one.
