Footstep Mode Dialog

Right-click anywhere in the Footstep track in Track View (Dope Sheet) to display the Footstep Mode dialog. This is a modeless dialog and can remain visible while you continue to work in Track View.

This dialog allows you to:

Interface

  • Edit Footsteps (The default.) In this mode, you can edit the biped’s footsteps to change their duration; start and end frames; airborne duration; and so on.
  • Edit Free Form (no physics) In this mode, you can edit the biped’s body keys for the frames at which the biped is airborne.

    Free Form suspends the physically based dynamics that normally control biped motion. This is essential when you want to make the biped fly, or sit down, or fall over. Note that the freeform period must be between footsteps.

    The freeform area appears as a yellow block between the footsteps.

Footstep Number Display group

The footstep blocks can have any one of four time settings displayed for them. You can show only one of these at a time.

The footstep step number is always displayed on the footstep blocks (in boldface).

  • Start and End Frame Displays the start and end frames of the footstep (from Touch to Lift). Biped displays just the start frame if the footstep block is too small to show both. Zoom in to see both start and end numbers.

    Both footsteps 0 and 1 begin at frame 0 and end at frame 19.

  • Start Frame Displays just the start frame number (Touch).

    Both footsteps 0 and 1 begin at frame 0.

  • Duration Displays the number of frames that the foot is in contact with the ground (from Touch to Lift).

    Both footsteps 0 and 1 are in contact with the ground for 20 frames.

  • Double Support Displays the number of overlapping frames in which both feet are in contact with the ground.

    You can also turn on the following two numbers for the intervals between the footsteps. You can display both numbers at the same time by selecting both boxes.

    Footsteps 0 and 1 share a double-support period of 20 frames.

No Support
Displays the number of frames that the whole biped is airborne; that is, the frames in which neither of the feet have any contact with the ground.

The no-support period between frames 3 and 4 and 4 and 5 is 12 frames.

Foot Air Duration
Displays the number of frames that each foot has no contact with the ground.

The foot air duration for the left footstep track between frames 3 and 5 is 31 frames.
