Function Curves in Biped

In ordinary 3ds Max animation, you’ve most likely encountered a situation where an object “drifts” a little between keys even though both keys are the same. This can also happen with freeform animation, where the foot or hand drifts a little between planted keys. In 3ds Max you generally solve this problem in Track View - Curve Editor, by adjusting function curves to straight lines going into or out of keys. New to 3ds Max 8, function curves are available for editing your biped motions. In previous versions, this task was difficult because biped objects are animated using Quaternion (tension, continuity, and bias, or “TCB”) controllers, which aren’t displayed the same way as Euler XYZ rotation controllers.
