Questions tagged [shape-keys]

Questions related to using and manipulating Shape Keys. Shape keys are used to deform objects by transforming the locations of control points over time. There are two kinds of shape keys, Relative and Absolute.

Shape keys are used to deform objects into new shapes for animation. In other terminology, shape keys may be called “morph targets” or “blend shapes”.

The most popular use cases for shape keys are in character facial animation and in tweaking and refining a skeletal rig. They are particularly useful for modeling organic soft parts and muscles where there is a need for more control over the resulting shape than what can be achieved with combination of rotation and scale.

Shape keys can be applied on object types with vertices like mesh, curve, surface and lattice.

Can I fix broken shape keys after editing basis?

I edited my mesh changing the number of vertices after adding shapekeys, and it get totally messed up when the shapekeys are on. Is there a way to solve this problem without remake the shapekeys all again!?

How to activate shape key by proximity of another object?

Like when you can use dynamic paint to apply displacement on certain parts of mesh and animate it like a brush stroke. My question is, whether you can activate a shape key the same way.

Is it possible to omit a vertex group from conforming to a shape key?

Is it possible to omit a vertex group from conforming to a shape key? I want to activate a shape key slider to change a mesh and have a selected vertex group stay in its basis position while the other verts around it conform to the shape key.

How to fix shape keys after having used symmetrize on the basis shape key?

I used "symmetrize" on the basis key because at some point I lost symmetry. It messed up all the other shape keys. I thought when you select a full model and click symmetrize it would just restore symmetry but it seems like it duplicates half of the…
