A lattice deformer includes two lattices: an influence lattice and a base lattice. By itself, the term “lattice” typically refers to the influence lattice. You create deformation effects by editing or animating the influence lattice. The lattice deformer’s effect is based on any difference between the base lattice’s lattice points and the influence lattice’s lattice points. By default, the base lattice is hidden so that you can focus on manipulating the influence lattice. However, remember that the deformation effect depends on the relationship between the influence lattice and the base lattice.
