Bimboing Blend Shapes
I set about creating the blend shapes for Bimbo - duplicating the lips and adding teeth (simple white plane) for when her mouth is open. Unfortunately I built the nice new shapes with duplicate pieces. So when I 'combine' the meshes (I seem to have to do this in order to blend) then it gets confused because the duplication wasnt made on the whole - I may have to go back a step or two to re-create the shapes :-(
I could just go back a few files and create blends using the pieces - so blend the top-lip then the bottom lip etc (drive key them even).
For blend shapes I referred to this tutorial by Larry Neuberger. This is short, sweet and has a cute mouse to boot.
