This intuitive tool lets you easily adjust the weights of selected vertices by dragging the mouse up and down.

The weights are automatically normalized while adjusting, so you can preview what your mesh will look like.

Ever had to rig an elbow or knee? This tool makes it much easier to get that perfect skin folding result!  
You can precisely control the weights on complicated areas under the influence of many bones like that.
Besides skinning with armatures, this tool is also useful for working with weights for things like hair density, physics goals, modifier influences etc.

All Blender versions are supported, including the latest release.

Latest version: 1.5.0 (July 2026)

• Added a new feature: optionally including the weights of locked bone groups when normalizing vertices.
  This is useful when you want to keep some bone groups locked, but still influencing the normalization of unlocked groups. 
  Please see the add-on preferences for the tooltip.
