Key Time Editor clip weights

The Weight property of each Time Editor animation clip determines how much of its animation plays in your scene. Setting keyframes on an animation clip Weight lets you blend the effect of the clip in and out, animating how much the clip influences the result animation at any given time. When two or more clips located on different tracks overlap in time and drive the same elements, you can mix them by setting weights that control their relative influence. This property is shown as a property of the Track and always reflects the weight at the current time.

When you adjust the weight of a clip, you control how much influence it has compared to the other clips in the resulting animation. The higher the mix weight, the more strongly the clip contributes to the animation.

When the weight is animated, a weight curve is created that you can adjust like any other animation curve. See Change Clip weighting.

The Weight curve shows on the clip in the Track View.

Note: You must have animation clips on more than one track to weight a clip's animation.

1. Move the Current Time Marker indicator to the moment in the animation clip where you want to set a keyframe.
2. Right-click the Weight field and select Set Key from the Time Editor Weight contexual menu.
3. Next, enter in a weight amount in the Track Weight field.
4. Click Set Key again.
5. Note: If weight values exceed the range of 0–1, the weight curve appears as a dotted line. You can set weights outside this range, but mix weights are averaged (normalized) by default, so that, for example, if Clip A has a weight of 1 and Clip B has a weight of 2 at a given frame, then A's influence is 33% (1 / (1 + 2)) and B's influence is 66%.
   Note: A clip weight of 0 stops the animation.
6. Continue setting weights on the clip.
   Note: You can use the Use Auto Key feature to key weights in the Time Editor. To respect the Maya Auto Key rules, a key must already exist for an attribute before you use Auto Key.
   The Weight field turns red to indicate that the default weighting of the animation has changed. A red curve on the animation clip shows the change.
   Note: Select Edit Weight Curve in Graph Editor from the Time Editor Weight contextual menu to perform detailed curve editing. See Graph Editor.
