Abstract: Embodiments of the present invention include computer-implemented methods and apparatuses for monitoring user activity and managing controllers in a 3-D environment that are provided herein. Exemplary methods may include: receiving user input in the form of user activity associated with a rigging of a character in a 3-D environment; monitoring the user activity, the user activity being indicated by a change in animation curve data; detecting a change in the user activity; identifying nodes associated with the change in the user activity, in which the nodes are controllers that are manipulated by the user in the rigging of a character in a 3-D environment; and adjusting the nodes such that the nodes are matched to the change in the user activity.
