The Lattice modifier deforms the base object according to the shape of a Lattice object. Objects to be deformed can be meshes, curves, surfaces, text, lattices and even particles.
A Lattice Modifier can quickly be added to selected objects by selecting them all, then selecting the lattice object last and pressing Ctrl-P and choosing Lattice Deform. This will both add Lattice Modifiers to the selected objects and parent them to the lattice.
- The Lattice object with which to deform the base object.
- An optional vertex group name which lets you limit the modifier's effect to a part of the base mesh.
Why would you use a lattice to deform a mesh instead of deforming the mesh itself in Edit Mode? There are a couple of reasons for that:
- The smooth deformation you get from a Lattice Modifier can be hard to achieve manually in Edit Mode.
When using a lattice to deform particles, always remember to place the Lattice Modifier after the Particle System Modifier. Read more about the importance of the modifier stack Here.
