Revit to UE -- LightMap issues? Broken UVs?

Hi all,

I am having an issue properly importing an FBX model from Revit. After importing the FBX model some of the geometries have what seems to be an issue with their UVs or Lightmap. To me it looks like the geos have stored lighting information from the Revit model.

I’m having some difficulty describing the problem in words as I don’t fully understand what the problem is. Please see attached photos.


This is what the static mesh looks like when I apply a material:

Check out it UV from here:

If you are using Lumen, then it not Lightmap.

It look like the polygon is overlaying each other and some material is wrongly assigned(but am not sure what the end result you are expecting).
