I've created blendshapes for the mouth of my character and they all work fine. I've now made eye blend shapes for him and tried to add them to the current deformer. However when I use any of the blendshapes for the eyes it moves the whole head upwards.
Ive made sure that the shapes are not parented before I add to the deformer but having no luck.
I can get around this problem by just making a new blendshape node but another problem arises where parts of the blendshape move even though i did not touch the vertexes of the target mesh.
I've tried creating the shapes again from the original geometry but even that does work
I've also made sure that the transforms are not frozen.
Advice would be much appreciated
