• In Unity editor, find the asset and "Show in Explorer"
  • Select the "FBX" file and import into editing software (All major modeling software supports FBX)
  • Material might not work, so needs a little bit of reconstructing

  • Carefully relink all the maps will do most of the time (because all the maps are put in a different folder so the modeling software might not recognize it)
  • It has a chance of breaking the prefab, so you might need to reconstruct the prefab for Unity again.
