WeightLattice

WeightLattice is a Blender addon that turns painted vertex groups into a lattice-based deformation workflow.

It is designed for artists and technical users who want a fast, controlled way to generate, edit, and finalize deformation cages directly inside Blender.

What WeightLattice does

• Creates a lattice from the active vertex group.

• Updates the lattice after weight painting changes.

• Creates a lattice directly from Edit Mode selection.

• Lets you edit the lattice shape and resolution.

• Applies or removes the lattice when the workflow is complete.

• Provides fast shortcuts for the most common actions.

Main workflow

1. Create or select a mesh.

2. Define the vertex group.

3. Paint the influence area.

4. Create the lattice.

5. Refine the cage in Edit Lattice mode.

6. Apply or remove the result when finished.
