io_scene_mk8muunt is a Blender add-on that imports and exports BYAML files from Mario Kart 8. It mainly adds panels to edit course information and visualizes object instances on the track as they appear in-game, loading the corresponding models with io_scene_bfres and transforming them as specified in the BYAML file. The add-on also tries to visualize advanced properties of the track, like paths.

Development of the add-on has ceased, thus it is not compatible with Blender 2.80 or newer versions, and not everything can be exported.


  • Import and export main course information.
  • Import and export areas.
  • Import clip areas.
  • Import effect areas.
  • Import lap routes (unfinished).
  • Import and export objects.
  • Import routes (unfinished).
  • Import sound objects.
