Credit to all, especially MarbleRaced for the marble pack.
Part three of the second season of the recently revived series, The Caddier Marble Race.

If you find a bug, report it to me. I will try to fix it, if I can. There is a bug where marbles might escape the course when in zero gravity mode. Luckily, there's an invisible plane that prevents marbles from escaping.

I also added extra collision layers just in case, and the marbles material names are now "Marble".
