Because it takes the game a little while to detect the Razor Hydra controllers I attempted to modify Nathans code to work for those with the controller, otherwise, it works fine.
-I moved Gym to Scenes folder
-Imported Strumpy Shader Editor to help us make shaders visually rather than in code (You can access it by clicking the Shader Editor button next to Terrain and Window buttons in Unity Editor)
-And attempting the "glow" effect for objects that you can pick up and if in range, they change color. Feel free to look at the torch as an example
