Nonlinear blendShapes is a technique were in between blendshape deforms from one shape to the other in a nonlinear way.

You can do this if yous wish with the exsisting nodes. If you wish.

ok, I'll bite. The only way I managed this in the past was with a plugin. Would love how to save that expense this time around. So how do you do non-linear morphs?

Ok this is how the basis interpolates.

now all you need is to make x number of extra blends that represents the additional targets and drive their value by the value of firts blend, by a basis curve function of your choice.

Also it is possible to pack this inside 2 blends so that it dont disturb the user and you only need 2 attributes.

It can also be pre solved with sufficient accuracy inside a single blendshape sliders value if you wish much like how nurbs are shown on screen as linar segnments but enough of them so you cat see the unlinearness of them.

if you neeed even more controll you can do it with a sooftbody and particle dynamics then you can do even quite much more complex morphs.
