WeightDial Lite - Free Exact Vertex Weights & Normalize

WeightDial Lite lets you type exact vertex-group weights on the selected vertices and Normalize them so every vertex sums to 1.

Lite stops at 2,400 vertices and Normalize. Full has no vertex cap, plus Limit Total, Clean, Smooth, Copy and Mirror X ($10), and brings per-vertex totals from 0.12-1.80 to exactly 1.00.
Remove Lite, install Full, done.

• Typed weights: each vertex group on the selection shows its average weight. Type a value and that group is set on all selected vertices.
• Normalize: rescales unlocked groups so every vertex sums to 1. Locked groups are left untouched.
• Add Demo: a 3-bone cylinder with uneven weights to try it on.
• Undo works, and each run reports how many vertices changed.
• Limits: meshes up to 2,400 vertices (the demo size).

1. Install: Edit > Preferences > Get Extensions > Install from Disk, pick weightdial_lite-0.1.0.zip.
2. N panel: select a mesh, enter Edit Mode, press N in the 3D Viewport and open the WeightDial tab.
3. Add Demo: click it to get a cylinder with uneven weights, already in Edit Mode with vertices selected.
4. Dial it in: type a weight on a group, then press Normalize.

• Lock a vertex group (the lock icon in the Vertex Groups list) to keep Normalize from changing it.
• Panel values refresh when you press Refresh Selection or run any operator.

On the demo cylinder (1,952 vertices, 40 selected, 3 bones), Blender 4.5 LTS:

• Typing 0.5 on a group sets 0.5 on all selected vertices.
• After Normalize, every vertex total is 1 within 0.000001.

• Blender 4.2-5.x (extension format). Tested on Blender 4.5 LTS.
• Mesh objects with vertex groups, in Edit Mode.
• Typed weights and Normalize only. Meshes over 2,400 vertices (the demo size) are refused.

WeightDial: Type Exact Vertex Weights is $10 and adds:

• Limit Total: keep the k largest weights per vertex.
• Clean: zero weights below a threshold.
• Smooth: relax weights over the mesh, renormalized.
• Copy From Active: copy one vertex's weights to the whole selection.
• Mirror X: +X onto -X, swapping .L/.R group names.
• Meshes of any size.
