importing mesh from Blender to UE5 (gapes in the edges of meshes)

I made a cube (one face removed) and added a silidifier modifier in Blender.

but when importing (fbx) to UE 5 I see a gap in the corners (edges).

am I missing something obvious. Appriciate the help.


You’ll want to check your normals. Make sure that you can’t see any red from outside the mesh.

(If this was in unreal, you wouldn’t be able to see the red face there)

I can’t be completely sure since you put the same blender image instead of the unreal one, but that’s my best guess.
