Youtube + Free Online Resources
This page is a link hub to online resources elsewhere. Hopefully, the following will have all you need to create interactive, immersive Unity visualizations, but if you find something useful, add it! Also, add the year + season you accessed it in order to keep the page up to date.
If you have a hankering to do things VERY chronologically, or feel you've missed something, this can be a great place to look!
Excellent rigging with barely any setup. Instead of adding hands as children to the controller object as in the tutorial, drag the hands asset into their respective 'prefab' slot on the XR controller component.
Great for discussions, drawing out examples. Somewhat pixelated and low quality though.
