Datasmith is not a solution for Maya users… since Datasmith only supports Deltagon .fbx format not maya .fbx, only way is to time and space consume with 3d software switching and converting file formats from maya to 3ds max to Datasmith to UE4, which is a terrible solution for this simple task of importing a model into engine.
Epic should include local pivot on FBX Import, look at Unity engine, it literally takes 1 second of drag and drop and that’s it, what i seen is majority of 3d artist usually group/parent/arrange their models inside 3d software and export a final game-ready model (.fbx or .obj most often) and then finalize the prop/model with applying texture/particle/code etc.
again, Epic! include Local Pivot, we want Local Pivot !
