Convert from Blender's coordinate system to Y-up

[darknoon]

USD likes to be Y-axis up, and coordinates in Blender are Z-up. Where in the process of export should we handle this?

When you save your translation, rotation or scale just swap [x,y,z] with [x,z,y] en with rotations [x,y,z,w] to [x,z,y,w] if quaternions.

USD and Blender are both Right Handed coordsys, so one problem less ;-)
