This add-on provides precise control over weight assignment by allowing you to scale weights interactively on individual vertices. It targets the active vertex group and calculates adjustments while attempting to maintain the original ratio between all other unlocked vertex groups assigned to the selection. The scaling strength can be tuned for finer control, making it useful for detailing edge loops and isolated vertices during rigging.
The tool operates optimally on normalized deformation weights. It does not automatically assign missing vertex groups or support symmetry mirroring during the scaling operation. Pushing the scaling to absolute extremes may zero out weights and disrupt the initial ratios. You can access the tool from the Mesh and Weights menus, though assigning a custom hotkey is recommended for a faster workflow.
