Animation blending is a linear blend between two poses in the local space of each joint. Think of it as a
mix function but applied to an entire pose. This technique does not blend animation clips; rather, it blends the poses that these clips have been sampled into.
When blending two poses, the entire pose does not need to be blended. Assume there are two animations—a run cycle and an attack. If the player presses the attack button, the top half of the attack pose is blended in over a short period of time, maintains a weight of
1 throughout the animation, and is then blended out near the end of the animation.
This is an example of using pose blending to create a running attack animation without having to animate the legs of the attack animation. The attack animation could be blended on top of a walk cycle for a walking animation. Animation blending can be used to transition smoothly between animations or to combine multiple animations into a new one...
