Hi cmercado,
Yeah that rig was created by me. Although I think Jonathan just took the full character and just deleted the middle section because it wasn’t needed for his project.
It was a custom rig, but a Rigify rig will work if you want to put it in game. There are some this you need to do though to make it game ready. I would suggest checking out Todor’s work on CGDive.com, he has some really in depth tutorials on Youtube and also has an add-on that automates a lot of the process.
If you want to start learning rigging, I would suggest the Fundamentals of Rigging
But if you want to learn rigify, I would suggest watching Todor’s stuff. He has a course you can purchase which is great (it also be available for free on Youtube but you should support artists if you can) https://cgdive.com/rigify/
Hope this helps.
