Weird Shading on Static Mesh
First thing to try is delete all post process and lighting, then create new ones. Afterwards, try to build lighting. If not working, try to put few default meshes from unreal engine in the scene and see it they render correctly. If so, your issue may be caused by bad normal from your source file (mesh from autocad or other softwares or downloaded meshes). As far as I experienced, the best thing to do is to re-model the mesh in Max.
