Lattice Auto Weighting is a Blender add-on that enables automatic weight assignment for lattice objects to armatures. It calculates weights for each lattice point based on its distance from the bones, allowing for smooth deformations without manual weight painting.

The tool provides several adjustable parameters, including the maximum number of bone influences per point, falloff values, and heat diffuse loops. Users can choose between traditional heat diffuse weighting and a voxelization-based method for complex lattices. The add-on also supports mask skinning to limit weight assignments to specific selected points. The operator is accessible via context menus or the standard Ctrl+P shortcut in object and pose modes.
