Blender Script - Bone Weight Merger


Has this happened to you? You want to reduce the overall number of bones in a model but weight painting is scary? Is the constant clicking required for setting up weight mix modifiers just not doing it for you?

This is a script that will merge (add) your goddamn weights and even clean up the old bones as well.

V2 is fixing some problems with autoapply/autodelete

The settings are at the top of the file.


  • Open script in blender text editor
  • Engage weight paint mode
  • Select all bones you want merged, with the mix target bone selected last
  • click [Run Script]
  • (optional) all vertex weight mix modifiers get applied automatically
  • (optional) the merged bones (except target bone) are deleted from the armature

Tested with 2.79 only
