Like an audio mixer where you add music tracks and use fades and blends to transition between tracks, the Motion Mixer allows you to mix motion clips. The Motion Mixer toolbar offers commands that you use to add and delete biped and non-biped objects to and from the mixer, modify clips, and change the way tracks in the mixer are displayed.

Interface

Add Max Objects

Opens the Max Objects To Mix dialog, which lists all non-biped objects in the scene. This dialog lets you add objects to be driven by your mixed animation, as well as name the mix in which they are contained.

This dialog is comparable to the Selection Floater.

NoteThe default mix name is the root node with the most children in the list.
NoteObjects can be added to only one mix at a time. Once an object is part of a mix, it is removed from the list.
Add Bipeds

Opens the Bipeds dialog listing all the bipeds in the scene. Highlight one or several bipeds to load them into the Motion Mixer window.

TipTo add multiple bipeds to the Motion Mixer, drag over any number of contiguous items in the list. If the items to add are not next to one another, hold down the Ctrl key while clicking the bipeds to add.
Delete

Deletes a selected biped from the Motion Mixer window.

Select

Lets you select bipeds, trackgroups, tracks, and clips.

Move Clips

Allows selection and movement (including Shift+Clone) of bipeds and trackgroups, keeping clips and transitions intact. It also allows independent horizontal movement of clips on the same track or vertical movement of clips from one biped's track to another biped's track.

Slide Clips

Allows horizontal movement of clips on the same track or vertical movement of clips from one biped's track to another biped's track. Sliding a clip to the right will move unselected clips which are situated to the right of the selected clip; sliding to the left will move unselected clips which sit to the left of the clip.

Offset

Records how many frames have been displaced. This value appears in the status area next to Slide Clips only during interactive translations, such as moving a clip or editing a time warp. The Offset value resets to zero when the translation is complete.

Frame

Displays the frame number under the cursor during interactive translations, such as stretching a clip or editing a time warp. When stretching a clip, you can use both the Frame and Offset fields to tell you how many more or fewer frames the clip will have.

Trim Clips

Clips can be trimmed from their original lengths interactively. When using this mode, you can grab the edge of a clip and drag it to a new frame within the clip’s original length. This mode will display all trimmed portions of clips in the Motion Mixer as gray. See Adjusting Clip Timing.

Editable Time Warps

Clips can be interactively time warped, given that they have had a time warp applied. When in this mode, you can place seams in a clip and then drag them within the clip’s original length. See Adding Time Warps.

Draggable Tracks

Enables vertical movement of tracks with clips. Holding down the Shift key while moving a track creates a clone of the original track.

Lock Transitions

When Lock Transitions is turned off (the default), moving a clip or changing its length on a transition track affect the lengths of transitions around the clip. When Lock Transitions is turned on, transition lengths do not change when you move a clip or drag clip edges not touching the transition. You can still change a transition's length by dragging the edges of the transition itself.

Set Range

Matches the active segment's start and end times to the extents of the mix.

Pan

Pans the Motion Mixer display horizontally and vertically.

Zoom Extents

Stretches or shrinks the mix to fit in the current Motion Mixer display.

Zoom

Allows horizontal stretching and shrinking of the display of the mix.

Zoom Region

Zoom into a portion of a track by dragging a region selection around that part of a track.

Snap Frames

An on/off toggle that sets the Motion Mixer to snap all adjustments to single frames.

Snap Clips

An on/off toggle that causes clips residing on the same track to snap together. The end frame of one clip will match the start frame of the next clip. If the first clip ends at frame 100, the start frame of the next clip will snap to frame 100.

When Snap Clips is on, transition edges snap to clip edges when dragged.

Preferences

Opens the Mixer Preferences dialog, where you can change display settings for clips, transitions, and frames.

Reservoir

Opens the Reservoir dialog.

Named selection

Lets you enter a name for the current selection. This field is similar to named selections for 3ds Max objects (on the main toolbar), but unlike named object selections, you can rename an existing set.

To create a named selection, select the clips for the set, enter a name in the named selectionfield, and then press Enter. You can reselect an existing selection set by choosing its name from the drop-down list.

Named sets of clips in the mixer are saved with the MAX file but not with MIX files.

Horizontal

This button is available when the Weighting button on the motion mixer toolbar or on a trackgroup is active. It locks all movement of weight nodes to the horizontal.

Vertical

This button is available when the Weighting button on the motion mixer toolbar or on a trackgroup is active. It locks all movement of weight nodes to the vertical.

Horizontal Vertical

This button is available when the Weighting button on the motion mixer toolbar or on a trackgroup is active. It allows free horizontal and vertical movements of weight nodes.

Weight Mode

An on/off toggle that allows you to work with weight curves. Weight curves are useful for making smooth blends between tracks. The Weight Mode button on the Motion Mixer toolbar acts as a global switch that toggles the Weight Mode buttons on every track in the Mixer. The Weight Mode button at the right end of each track toggles weighting only for that track. For more information on how weight curves work, see Motion Mixer Editor. To find out how to use weight curves, see Adjusting Track Weight.
