Poses

In addition to animating the parameters of objects in a scene, you can also define poses. Poses do not evolve over time, but are applied as deltas to the basic animation. When a scene is embedded in another, the embedded scene's poses become available as extra scalar parameters on it -- each pose parameter represents a coefficient applied to the pose's deltas. Setting the coefficients of multiple poses to nonzero values lets you mix and match them.

When editing a scene directly, its poses will most likely be available as a list in a tab in the properties pane; selecting a pose other than "Neutral" will show the animation with just that pose's deltas added in, and any changes made to parameters will change the pose deltas rather than the base animation.
