5 In the modifier stack display, choose Control Points as the
sub-object level for FFD(box).
6 Adjust the control points.
NOTE The distortion effect of an FFD modifier is based on the positional
offset of the control points from their original positions in the source volume.
If you don't move control points, there is no effect on the target object. Keep
this in mind when using space-warp version of the FFD.
If you're using the Deform group > All Vertices option, once you've distorted
the object you can set the Falloff value to adjust how much the lattice affects
the object, based on distance. This is particularly useful if the lattice is animated
to approach or move away from the target object. When Falloff is set to 0, all
the vertices are affected, regardless of distance.
NOTE When you're at the base-parameters level of an FFD modifier in the Stack,
the Show End Result button is turned off and spring-loaded, as it is in an Edit Mesh
modifier.
