Default In/Out Tangents For New Keys

Status bar Animation controls Default In/Out Tangents For New Keys flyout

This flyout provides a quick way to set a default tangent type for new animation keys created with Set Key Mode or Auto Key Mode. You can also access the tangent types from the Key Info (Basic) rollout and the Curve Editor's Key Tangency toolbar.

NoteChanging tangent types does not affect existing keyframes, only new ones.

On each new set keyframe, the Key Tangent flyouts on the Key Info (Basic) rollout updates with the current default tangent type.

When you set a default tangent type, both the in and out tangents are set to match that type. If you set different in and out tangents via the Controller Defaults group of the Animation Preferences panel, the current flyout icon changes to a question mark.

NoteSetting a default tangent type stores it in the 3dsmax.ini file, from which it is restored after a scene reset or session change.

Procedures

Example: To set a default tangent type:

  1. Create a sphere.
  2. Turn on (Auto Key), go to frame 10, and move the sphere on all three axes.
  3. Right-click the sphere. From the quad menu, choose Curve Editor.

    The position curve with Flat tangent.

  4. Choose the Linear tangent type (second icon from the top) from the Default In/Out Tangents For New Keys flyout.

  5. Go to frame 20 and move the sphere elsewhere in your scene.

    The curve starts curvy at frame 10 but straightens out near frame 20. Its interpolation transitions from an Flat out tangent to a Linear in tangent.

  6. Go to frame 30 and move the sphere again.

    The curve interpolation from frame 20 to 30 is straight because both keys have tangents set to Linear.
