Can't Delet eMesh

Hi Knowledgeable People,
I am new to UE and floundering here!
I have imported a model from Blender however some of the walls of one of the static meshes is translucent. I can see shadows through the surface on to the inside. This body should be solid and opaque. The materials shows opaque in the blend mode settings.
Any clues appreciated.

Your subject doesn’t match your question and you posted in Feedback for the Unreal Engine team and Feedback about the documentation which might be why you’re not getting any answers.

Sounds like you might have flipped normals, but I can’t tell without a screenshot.
