I have a UVW Mapping modifier applied to a box. The box also has a squeeze modifier on it that compresses the box and then expands it.
I have tried keying it with the gizmo under the subtree of the UVW mapping modifier selected, but it only let's me key in one direction: either the gizmo gets bigger or it gets smaller, it can't do both. Also, the gizmo does not centre around the box.
