yep yep. There's actually an MfnBlendshapeDeformer class that I can use to set the values between 0 and 1. But I'm not finding one to effect the individual weights of the components. It should be possible considering you can paint the weights and edit them in the component editor. I would imagine they added some way to do this through API, but maybe not. I might have to do this the old fashion way.
