Lattice Magic is an add-on by Mets that brings two major lattice-based deformation tools, along with some minor lattice utilities, to Blender. Tweak Lattice deforms a set of mesh objects in a way similar to Proportional Editing, except the deformation is driven by an object in 3D space that can be parented to a deforming character, follow their armature deformation, and be animated. Camera Lattice deforms a collection of objects from a particular camera perspective, like Liquify but operating on vertices instead of pixels; its lattice points cannot be animated, so the add-on provides a workflow for managing a set of shapekeys and their keyframes.
Both tools were designed for character animation tweaks in a production environment and fully work with linked and overridden animated characters. Version 1.0.1 introduced an automatic parenting option, set as the default, which parents the lattice to the same bones as the deforming bones of the nearest vertex to the cursor; the manual parent-selection method remains available. This release also replaced the fall-off expression with preset fall-off shapes such as Linear, Smooth, Root and Sphere, and added poll messages so the UI explains when an operator isn't available.
