Extended bicubics have additional vertex channels that appear in the Channel Editor for subdivided vertex
channels. These channels appear only when you create a keyframe for the channel and its value changes.
These vertex channels are named vertex_0.1, vertex_1.0, vertex_2.1, and so on, according to their position
on the surface. Click the vertex on the surface to highlight its channel in the channel hierarchy. See
Warping
an Extended Bicubic Surface
