You can assign different controllers to the tracks, affecting the way they respond. The Bezier Controller, assigned by default to all the Position tracks, lets you move objects using the Select and Move transform tool, and converts those movements into Bezier splines. You can adjust the splines in Function Curve editing mode. Animation Layers When you animate a biped or other object, you can add layers of animation above the original biped animation. This is a powerful way of making global changes to your animation. For example, when you add a layer and rotate the spine forward at any frame, a run cycle becomes a crouched run. The original biped motion is kept intact and can be viewed by switching back to the original layer. You can view layers individually or as a composite of all the animation in all the layers. Layers behave like a freeform animation; the object can adopt any position. Layers used in conjunction with Biped let you easily adjust raw motion-capture data, which contains keys at every frame. You do this by adding a layer and keyframing the biped. Layer controls for Biped are on the Layers rollout on page 4403. For other objects, use the Animation Layers toolbar on page 7508. Applied IK A type of inverse kinematics where one or more parts of the IK structure follows another animated object exactly. After the scene is set up, Applied IK generates transform keys for every object in the IK chain. See Animating with Applied IK on page 3462. Area Lights (mental ray Renderer) Area lights are a feature of the mental ray renderer. Instead of emitting light from a point source, they emit light from a broader area around the source. Area lights create soft-edged shadows. This can help improve the realism of your rendering. Glossary | 7909
