Well... the main reason I did it this way was so that I could effect all the clothing meshes a too. It's a for a crowd system and the model has like 10 different clothing meshes stacked on top of each other which get called by the crowd system depending on the randomizer. The lattice made a super easy way to convert them all to the hourglass shape.

But it does kind of seem like there isn't an easy way to remove the lattice without deleting the history...
