Hint: Since Blender 2.67 we have bone weight copy tools (in the weight paint tool shelf). We seriously recommend to upgrade to Blender 2.68

for Blender-2.59 up to Blneder 2.66 we have a weight copy Addon for you.

CAUTION: This addon must not be used with Blender 2.67 or newer !!!


Bone Weight Copy

The only reason why this addon exists is because Blender had this functionality missing.

Further reading



  • Download the Bone weight Copy addon (enhanced version for OpenSim and similar online worlds). The exporter is packed into one single python file.
  • Open Blender’s addon installer and Install the downloaded file just like you do with any other Addon


There is no support available for this module.

Warning: This addon does only work in Blender 2.59 up to 2.66!
