1. Unzip the File.
2. Load the blendfile/template for female or male model.
3. Import the OBJ.
4. Click on the "Run script" icon (the "Play button" icon) in the text window (the window showing
the script) titlebar to run the script.
5. Export the OBJ, but disable "Materials" in the "Geometry Export" settings on the exporter (else you get
your UVs sorted into UDIM tiles, but still split per material in Substance Painter).
It's a "One Trick Pony", if you converted a OBJ (or even just loaded one, I think), then load another one to convert,
it will give you an error. You can work around it, easiest way is: reloading the template (opening the blendfile again).
