Weight Paint Tools provides an expanded set of operators for vertex weight editing in Blender. The add-on introduces a dedicated pie menu for managing weights, alongside a custom colored 3D viewport overlay that allows users to preview all vertex weights simultaneously.

It includes tools for copying and pasting weights between vertices, transferring weights between bones with various blend modes, and generating gradient weight distributions with multiple falloff options. Additionally, the toolset features specialized mirroring operations, including a mirror project function that can symmetrize weights across non-symmetrical topology, and the ability to project weights from unselected mesh parts onto active selections.
