So that image would be the weighting for the right side with 0.5 for the middle, and getting smaller by 0.1 going left, and vice versa.
Also, I'm getting some weird things happening when I modify the "blendshape deformer" attribute in the component editor of the vertices. For some reason, after I alter those values in the component editor and either delete the blendshape or history; any new or old blendshapes will no longer work. Unless I change the "tweak" attribute to an envelope of 0. However, if i havn't touched the component editor, the blendshapes will work with a "tweak" envelope value of 1 (the default). Why is that?
