As you play Animation Sequences on your Skeletal Mesh, you may find it necessary to animate additional properties and values synchronized to that animation. You can accomplish this using Animation Curves (also called anim curves, or curves), which are float-type values you can add and keyframe within an Animation Sequence. Curves can be useful for augmenting your animations with additional animatable properties, such as animating Material Parameters, Morph Targets, and other attributes.
