Mac OSX Sierra - Asset Forge 2.1

Export Model - chose Godot, GLTF which defaulted to X is Up and Export Textures checked. A second 3D image model appears in the main window inverted!! (I assume because X is Up). So now the main display has two models displayed. If you would like I can send you screen shots.
