Why has the Twinmotion Boats Pack 1 been removed from Sale even though it was free ??

I don’t know if sharing such asset is allowed since it’s been removed form sales … anyway I got this asset and I’m trying to use it but unluckly in 5.1.1 and 5.2.1 it has some issues:

When building lights I got such messages:

No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results.  Please add a tightly bounding lightmass importance volume to optimize your scene quality and lighting build times.

SM_Yacht02 Object has overlapping UVs.

SM_Yacht02 Lightmap UV are overlapping by 65.7%. Please adjust content - Enable Error Coloring to visualize.

And the final result is this:

And btw the black boat is not one of those reported in messages.

P.S. I tried adding the lightmass importance volume without any luck…

Best regards,
Mike
