Figure 7.14 Masking and rotating with Transpose can create unnatural bends

(a, b). Bone posing used to bend an elbow creates a more natural effect (c).

Adjusting the Intensity slider can have unexpected results since the blend is closer to

a blend shape deformer than rigged animation. The figure will blend between its two posi-

tions by letting the vertices take the shortest path. The Intensity slider works exceptionally

well when storing blend shapes for facial animation in layers (Figure 7.16). ZBrush can be

used to sculpt facial animation targets; adjusting the intensity on the layer allows you to

export different intensities of targets as well as blend target layers together.
