I’ve encountered this problem before as well, but I could not find a solution.
The model I’ve created on Blender looks fine, but on exporting it to Unreal Engine, some faces of the mesh appear as if they are facing towards the inside of the mesh. If there is a way to fix this that does not involve recreating the mesh from the start up, then please let me know.
Edit: Never mind. **FIXED IT. **Sorry!
