Additive Blendshapes 2003-11-22 - By Ultraloveninja
Back
since you are using SDKs they are nothing but curve relationships
between attributes so you could examine
and tweak the curves in the graph editor to make sure your SDKs work
the way you want.
Beyond that you might have to write expressions to fix it
I hope this helps
