WeightLattice

Paint. Press Enter. Reshape. Apply.

WeightLattice is a Blender addon that turns a painted vertex group into a lattice cage in one keystroke. It replaces the manual lattice setup — create lattice, scale, position, add modifier, assign vertex group — with a four-step workflow driven entirely from the viewport.

How it works

1. Select a mesh and click New Weight Lattice.

2. Paint the area you want to deform in Weight Paint.

3. Press Enter — a lattice cage is generated around the weighted region, already linked to the mesh.

4. Reshape the cage, then press Enter again to apply (or ESC to discard).

Multi-mesh workflows are supported: selecting more than one mesh builds a single cage shared across all of them.

Compatibility
