It is awkward but that’s why it’s important when creating your meshes and building scenes in any 3D modelling software, you keep it’s origin and orientations in the forefront of your mind and build accordingly. Doing so will save you a mound of frustration down the road. It’s also easier to compartmentalize your assets, bring each piece into UE4 then build your scene there rather than build an entire world in your modelling software and import it as one big static mesh.
