FBX Bundle is one of those free Blender add-ons you really need to add to your toolkit. It enables you to do one click exports to game engines such as Unity and Unreal, as well as COLLADA and glTF. It also enables you to automatically perform tasks like LOD generation, AO, collision meshes and more. It also automatically handles z-axis issues on export.
