This is a test to see if the positioning, scale, and orientation holds when I export the STL file. So the default export from Cheetah3d shows a top view in the VRM360 plugin. I can set rx=-90 to match the orientation in Cheetah3D. I also match the aspect ratio to 1.5 and initial offset to 1.7. This mostly centers the object and keeps it close to center when in full screen mode given a landscape 16×9 (16×10) screen.
