The Hawk Rig originally functioned well enough, but it had some scaling issues that made some of the wing flex animation appear wonky, and the controls weren’t exactly clear in their purpose.
So I rerigged it to fix the scaling problem and then created a more clear layout for the controls, as well as adding some stretch capability to the wings so that they could enhance the silhouette.
The Rig is mostly fairly self-explanatory, with basic wing controls to allow the different parts to bend and twist, as the Hawk only appears briefly in the film and is mostly moving in dives or glides, he didn’t need excessively complex components.
This tutorial by Mike Hermes formed the basis for what I chose to do, though I simplified it immensely.
