Maya display units
If you change working units from cm to e.g. meter.
One issue you’ll face is that this is only display units.
Maya does everything in centimeters. Your exports will be in the wrong units depending on your exporter.
Bob White:
I try to leave everything as defaults in the DCC apps (being bitten by to many 3rd partly plugins being stupid).
If conversions need to happen I like to do it as a post-process step on the export data.
In the best world, you’d actually do it as a pre-process step on import, that way your export data can be round tripped more easily.
Had a lot of luck using https://help.autodesk.com/view/FBX/2020/ENU/?guid=FBX_API_Reference_cpp_ref_class_fbx_axis_system_html for both imports and exports in our world editor at volition.
