Some of the topics included:
1. Creating a manual setup
2. Saving out a subgraph from that manual setup
3. Creating a Eye Rig template using the Rig script component
4. Creating a reusable HDA that can be used on any rig
I've also provided a link to the finished rig in the video description, in case you just feel like grabbing the rig.
Hope you find it useful
