After Figure Mode, in the Controller tab: adjusting Biped controller shape, NURBS Curve scale, left/right mirror, custom controller creation (Origin/Selected/Offset), and setting naming prefix and suffix.
Prerequisites
- Build + Figure Mode (Init) completed
- Joint positions re-aligned in Figure Mode if necessary
Step-by-Step Guide
1. Controller Tab Overview
- This is the phase of refining controller position and shape after Build.
- If the controller display (flags) becomes misaligned after changing positions in Figure Mode, they can be re-aligned in the Controller tab.
2. Biped Shape Editing
- Enter Biped Shape edit mode.
- Move vertices to adjust the controller size and form.
- Press Update to apply the changed shape.
- For the other side: switch to Flip mode for editing → use the R key to find the matching Left/Right name and confirm that the other side changes as well.
3. NURBS Curve Bulk Scale
- NURBS Curve controllers have their source, curves, and points bundled together, so scaling them only in Max can slow things down.
- Adjust size using bulk scale in the Controller tab.
- Apply the same to the other side after Flip.
4. Custom Controller Shape
- You can create a custom shape in any form you want (detailed in the latter part of the video).
5. Controller Creation Modes
| Mode | Description |
|---|---|
| Origin | Nothing selected — created at world origin |
| Selected | Created at the position of the selected bone/object |
| Offset | Created at an offset position relative to selection |
- Hiding the character first and pressing the button allows testing like creating in an empty scene.
- The Selected + Offset option combination also enables group-level placement and rotation.
6. Naming (Prefix · Suffix)
- Use Prefix / Suffix to align controller naming conventions.
- Symmetric option — both side names are automatically changed according to rules like Left/Right.
- Changing only the prefix triggers a bulk rename on both sides.
Recommended Rules
- Things that animators directly interact with → add a prefix meaning "controller" at the front of the name (varies by team, e.g.,
Ctrl_). - Check team guidelines to avoid conflicts with Biped's default root names.
Concept Reinforcement
- The Controller tab is the "polish visuals + team naming" phase — the rigging functionality itself has already been determined in Build/Figure.
- It is common to alternate between re-adjusting joint positions in Figure Mode and refining shapes in the Controller tab.
Notes
- Don't forget to Update after editing Biped Shape.
- Modifying only one side without Flip mode will cause left/right shapes to differ.
- Naming rules must match production standards for Picker, Mirror, and export to be consistent.
