Can't select everything in edit mode When I'm trying to import this mesh into UE4 (the mesh is a wooden chest). I keep getting missing faces and I've seen people say it's due to Blender and that I should try going in edit mode and select everything with A then press CtrlN, but when I get in edit mode and press A, it only selects the lid or the base of the chest. The part not selected is underlined red so I'd assume it's related.
You can check, the normals, and also what kind of polygons are better with ue4, quads or triangles.As for the a key, I don't know.Do you use any version under development.The official is 2.78c
