Point Controller Container

The Point Controller container controls point sub-objects within editable splines, editable surfaces, and FFD (free-form deformation) modifiers.

The Point Controller Container 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, NURBS surface, or FFD (Free-Form Deformation). 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.

In Dope Sheet mode, the Point Controller Container is displayed as a track with green keys in Track View. Sub-tracks below the main track contain all the animated vertices, control points, and vectors.

Procedures

Example: To animate vertices, viewing the Point Controller Container track:

1. In the Front viewport, create a sphere.
2. Right-click the sphere and from the quad menu, choose Convert To Convert To Editable Mesh.
3. On the Editable Mesh Selection rollout, click Vertex.
4. Turn on , and drag the time slider to frame 10.
5. In the viewports, select and move some vertices on the sphere.

   A key appears on the track bar at frame 10.

6. Right-click the sphere, and from the quad menu, choose Dope Sheet.

   3ds Max opens the Track View - Dope Sheet. At the top of the Controller window, you can see the tracks for the sphere.

7. Expand all the Sphere tracks in the Track View hierarchy.

   Track View displays the Point Controller Container track, with tracks for the animated vertices below it.

Interface

Pointer Controller Container Track Keys

In Track View – Dope Sheet mode, clicking a point controller key (green) highlights all sub-keys at that frame.

If hundreds of vertices are animated, collapse the track so that only the top track is visible. Moving a green key moves all of its sub-keys.

Key Info dialog

Right-click a green key in Track View to open the Key Info dialog, which provides access to all sub-keys under the main entry at a given point in time.
