To create animation in an FBX scene, you must use several closely related FBX classes: KFbxAnimStack, KFbxAnimLayer, KFbxAnimCurve, KFbxAnimCurveNode, KFbxAnimCurve, and KFbxAnimCurveKey.
Before FBX SDK 2011, the data structures for animation were the take node (or take), the take node container, take info, among others.
