Thanks for the offer but we got it all fixed now.
Was a few little leaf patches that where sharing the same UV space but where welded.
So UE4 couldn’t generate working lightmap UVs from it.
We now imported them manually, works fine now.
Now recompiling the example maps tonight / tomorrow and getting all ready for mondays release.
cheers
