• Reset Pivot [Bool]
  • Centers the pivot of decombined meshes, if disabled the meshes have a pivot set to 0,0,0.
  • [WARNING]: Pivoting meshes sometimes causes major position offsets.
• Reset Scale [Bool]
  • Resets the scale of the decombined renderer which fixes position offset issues, though can mess up other things.
  • [WARNING]: Disabling this option can lead to position offsets in the final decombined mesh.
• Fix Colliders [Bool, Requires Reset Scale to be Enabled]
  • Moves colliders on the root object to a child object with a corrected scale value to fix issues from Reset Scale.
  • [WARNING]: Disabling this option can lead to incorrectly sized colliders in the final decombined mesh if they exist.
• Fix Children [Bool, Requires Reset Scale to be Enabled]
  • Corrects an object's children when resetting the parent's scale.
  • [WARNING]: Disabling this option can lead to incorrectly sized children.
• Set Meshes Static [Bool]
