Description

The aiBlendshapeAdd script works by automatically adding blendshapes inbetweens and optionally controllers and attributes. This is done using a naming convention:

Bsn_Mouth_HappySad_100p
Bsn_Mouth_HappySad_50p
Bsn_Mouth_HappySad_100m

Will create blendshapes, build a Mouth_Ctrl node, add a HappySad attribute and and connect it all up.

This allows you to easily rebuild your blendshape setup after changes and try out different weightings.
