The Master Point controller is assigned automatically whenever control points, vertices, or vectors (tangent handles) are animated in the sub-object mode of an Editable Spline, Editable Patch, Editable Mesh, Editable Poly, or FFD. By allowing you to select and move all the sub keys, visually correlate keys to points in the viewports, and change key properties quickly, this controller helps to manage the numerous tracks created when animating vertices, control points, and vectors.
The Master Point controller displays as a track with green keys in Track View. Sub tracks below the Master track contain all the animated vertices, control points, and vectors.
Procedure
Example: To animate vertices, viewing the Master Point controller track:
In the Front viewport, create a sphere.
Right-click the sphere and select Convert to Editable Mesh in the dialog.
On the Editable Mesh > Selection rollout, click Vertex.
On the Editable Mesh > Soft Selection rollout, click Use Soft Selection.
Turn on Animate, and move the time slider to frame 10.
In the viewports, select and move some vertices on the sphere.
A key appears on the track bar at frame 10.
Right-click the sphere, and select Track View Selected in the dialog.
Track View displays with the sphere at the top of the Track View Hierarchy window.
Expand all the sphere tracks in the Track View Hierarchy.
The Master Point Controller track displays, with tracks for the animated vertices below it.
Interface
Master Track Keys: Selecting a master key (green) selects all the sub keys at that frame.
If hundreds of vertices are animated, collapse the master track so that only the master track is visible. Moving the green keys will move all the sub keys.
