Both the Inertialization and Dead Blending node tracks the animation pose motion and changes within Animation Curves, so that the motion can continue moving toward the target animation when an inertial blend is activated. These nodes are activated by any inertial blend requests connected to its Source input pose pin. State Machine Transitions, Blend Nodes, Linked Anim Graphs and Linked Anim Layers, can all trigger inertial blends. The Inertialization or Dead Blending node must be connected after the source of the inertial blend request, but does not have to be immediately adjacent. Deferring an Inertialization or Dead Blending node closer to the Output Pose node can help reduce or eliminate standard blends from your graph and improve your animation system's performance. A single Inertialization or Dead Blending node can handle many inertial blend requests. When processing multiple inertial blend requests, the minimum requested blend duration will be used.
