Overlapping lightmaps are generated when the LOD group is not the default. Setting the LOD group to None and rebuilding lighting doesn't have the same result.
Found in 4.24 CL# 10570792
Reproduced in 4.25 CL#10719465
1. Import the attached mesh. Don't create lightmaps on import.
2. Place the chair in a level.
3. Build lighting.
4. Open the chair mesh and change the LOD group to Large Prop.
5. Rebuild the lighting.
6. Look at the chair.
Result: Overlapping UVs are generated.
Expected: Overlapping UVs are not generated.
