Strange texture problem

Hello. New to unreal, I’m testing the Modo-Unreal workflow with and without the Modo Bridge. My uv’s are all nicely setup in Modo, named 1_texture for the textures and 2_LM for the Lightmap baking, no overlap.
In modo, the textures display correctly, even with a UV test image (color grid with numbers) but when I import my meshes (FBX) into unreal, some are all messed up *walls and ceiling in this case) Any idea?
Thank you

Check if the uv maps in unreal are the same as in modo.

Yes, they are.
