Developer Note

• Project is locked during the PostSaved event
  • Substance painter hide a python api _substance_painter.project.do_action(_substance_painter.project.Action.Unlock) for project locking/unlocking
• Python API cannot access current export options
  • Javascript API can
  • Check the document by Help - Scripting Documentation - Javascript API in substance painter application
• Javascript API alg.settings is undefined
  • So export_on_save_settings.json stored in the same directory with the plugin python file is used instead
• There is always a warning about deprecated method _utility.make_callable
  • It is called by TextureSet.name() which is a sustance painter python API internal method
  • As a walkaround, just use the hidden python API _substance_painter.textureset.material_name
• So many hidden API, substance painter's plugin api seems to be a shit
  • YES, F**K AD@BE
