Preparing to Create Footsteps Manually

Before placing footsteps, you must choose the gait, then set parameters for the gait in the Footstep Creation rollout.

When you select the Walk, Run, or Jump gait, parameters for that gait appear on the Footstep Creation rollout. See Choosing a Gait for information on gaits and parameters.

Switching Between Left and Right Footsteps

By default, manually placed footsteps alternate left, right, left, right. The footstep cursor, which appears during individual footstep creation, shows you whether a left or right footstep will be placed next.

If you want to change the footstep side that will be placed when you next click, press Q to toggle between them. Pressing Q also changes the cursor, showing you which footstep side will be placed next.

Automatic Time Extension

During manual footstep creation, your display remains at the current frame. However, footsteps are created sequentially in time. If the footsteps you create require more frames than are in the active time segment, the footstep creation process extends the active time segment, which can create new frames.

Creating New Footsteps Between Existing Footsteps

If inactive footsteps exist, you can only create new, inactive footsteps within or directly before or after the time of the inactive footsteps. If you need to add more footsteps near a time where there are only active footsteps, deactivate all footsteps first, then add footsteps and activate them again. See Deactivating Footsteps.

Procedures

To prepare for manual footstep creation:

1. On the Motion panel Biped rollout, click (Footstep Mode).

   You are now in Footstep mode, and can create, activate, or edit footsteps.

2. In the Footstep Creation rollout, choose the gait you want to use: Walk, Run, or Jump. See Choosing a Gait for details on gaits and their parameters.
3. In the Footstep Creation rollout, set parameters for the chosen gait.

To create footsteps beginning at the current frame:

1. Turn on (Footstep Mode).
2. Click (Create Footsteps (At Current Frame)).
3. Click in a viewport to create a footstep. Move the cursor and click again to create another footstep. Repeat until you have created all the footsteps required.
   TipUse the Top viewport to create the footsteps.

   Watch the footstep cursor to see whether a left or right footstep will be placed next. If you want to place two left or two right footsteps sequentially, place one footstep, then press Q once before placing the next one.

4. Move and rotate footsteps until you have achieved the desired pattern.
5. Click (Create Keys For Inactive Footsteps).
6. Click (Play Animation) to see the animation.

To append footsteps onto the existing footsteps:

1. Make sure (Footstep Mode) is turned on.
2. If the existing footsteps are active, deactivate them first. Select all footsteps and click (Deactivate Footsteps).
3. Click (Create Footsteps (Append)).
4. Click in a viewport to create a footstep. Move the cursor and continue clicking to create more footsteps
   TipA Top viewport is usually best when you create footsteps individually.
5. Move and rotate footsteps until you have achieved the desired pattern.
6. Click (Create Keys For Inactive Footsteps).
7. Click (Play Animation) to see the animation.

To create footsteps using AutoGrid:

The AutoGrid feature creates objects on a surface other than the default construction plane. You can use this feature to place footsteps on an irregular surface.

1. Using any 3ds Max modeling method, create a surface as the terrain for the biped to step on.
2. On the Create panel, click (Systems), then on the Object Type rollout, click Biped.
3. On the Object Type rollout, turn on AutoGrid.
4. Go to the Motion panel.
5. On the Biped rollout, turn on (Footstep Mode).
6. Click (Create Footsteps (At Current Frame)). Move the cursor over the terrain. A transform gizmo moves with your cursor to indicate the location and orientation of the gizmo. Click to place a footstep, then move the cursor and click again to place more footsteps.
7. When you have finished placing footsteps, click (Create Keys For Inactive Footsteps).

   Keys have now been created for the footsteps.

8. Click (Play Animation) to see the animation.
