This is the edited object source code that produces the animated part c_wheelsteer in fxpaint.mdl.

Note the Call32( ... ) command just before the Return command at the end of this code. This is where the "Child Parts" of the rudder are called. This assures that the animation applied to the rudder is also applied to those parts which use the rudder as a parent part.
