Blendshape + Animation = Weird Error

I'm doing tests with the Genesis model of the DAZ program, this model has blendshapes to change it:



I have been testing a morph that transforms it from adult to young. But this strange error appears when I play a running animation and turns the model into a kind of monster from Dead Space.



The animation is from this asset:

Does anyone know what is going on? Can someone help me solve it, please?

 

Up.

Please, can anyone help me?

 

I have done tests and the problem are the bones. When applying the blendshape in the mesh, the bones in Unity are not updated and cause that error. I mean, when the mesh becomes small, the bones would have to follow that modification to not deform.

Am I doing something wrong or Unity is not compatible with blendshapes that modify the mesh a lot? In the DAZ program I can apply that blendshape with an animation and the model doesn't deform.

 

They gave me a solution here, using the UMA asset:
