I am trying to delve deeper into Lattice for modeling and I have so far been able to isolate the modeling area that the Lattice performs its deformation on by creating a vertex group on the mesh. When I add a Lattice deformation modifier to the mesh, I assign the Lattice and then the mesh vertex group. So that works great.
However, I was wondering, how do vertex groups work on the Lattice itself, since you can see two areas, one where you can create Vertex groups (as well as Shapes) and above it, where you assign the vertex group to use as an influencer.
Could someone please explain and possibly give an example of use for these?
