.. _bpy.types.LatticeModifier: **************** Lattice Modifier **************** The Lattice modifier deforms the base object according to the shape of a :doc:`Lattice ` object. Objects to be deformed can be meshes, curves, surfaces, text, lattices and even particles. .. tip:: A Lattice Modifier can quickly be added to selected objects by selecting them all, then selecting the lattice object last and pressing :kbd:`Ctrl-P` and choosing *Lattice Deform*. This will both add Lattice Modifiers to the selected objects and parent them to the lattice. Options ======= .. figure:: /images/modeling_modifiers_deform_lattice_panel.png Lattice Modifier. Object The :doc:`Lattice ` object with which to deform the base object. Vertex Group An optional vertex group name which lets you limit the modifier's effect to a part of the base mesh. Strength A factor to control blending between original and deformed vertex positions. Hints ===== 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: - If your object has a large number of vertices, it would be difficult to edit portions of it quickly in Edit Mode. Using a lattice will allow you to deform large portions efficiently. - The smooth deformation you get from a Lattice Modifier can be hard to achieve manually in Edit Mode. - Multiple objects can use the same lattice, thus allowing you to edit multiple objects at once. - Like all modifiers, it is non-destructive. Meaning all changes happen on top of the original geometry, which you can still go back and edit without affecting the deformation. - A lattice does not affect the texture coordinates of a mesh's surface. .. note:: When using a lattice to deform particles, always remember to place the Lattice Modifier after the Particle System Modifier.
