Import:
The generated USD will be set with up axis = +z as that's the most common for stl files.
Export:
exportAscii: If true, the stl file will be in ascii format, otherwise in binary format. Example:
#usda 1.0
(
doc = "Blender v3.1.2"
metersPerUnit = 1
upAxis = "Z"
customLayerData = {
bool exportASCII = false
}
)
