Detailed Description

An animation channel that accepts a matrix each frame from some dynamic input provided by code.

This object operates in two modes: in explicit mode, the programmer should call set_value() each frame to indicate the new value; in implicit mode, the programmer should call set_value_node() to indicate the node whose transform will be copied to the joint each frame.
