The first step should always be to gather more information on exactly what went wrong. In the case of SEUT, if there is no error popup, this means checking the SEUT Notifications-screen. There you can filter all notifications by type and thus should be able to easily find errors and warnings. Errors in that screen also contain a button with a link to the list below, which provides solutions to fix all errors. Should no relevant error or warning be listed in the SEUT Notifications-screen, click the Export Logs-button and look at those.

If you cannot find an answer to your issue, or if you find something marked Traceback in your log files, your next step should be to search through the open GitHub issues here. If you cannot find an issue pertaining your particular case, feel free to open up a new issue, including your full logs.

  • enenra - Main developer and author of most of the functionality.
  • Stollie - So much general help but also writing everything character, export and MWM-related, which I wouldn’t have been able to do at all.
  • Harag - Writing the original Blender SE plugin. A lot of code in this addon is based on his.
  • Wizard Lizard - For hours of testing as well as writing the SE Texture Converter to save us all from having to deal with batch files.
  • Kamikaze (Blender Discord) - Writing the remapMaterials()-function and generally helping out constantly by answering a lot of questions.
