This is just a course for Epic Marble Races' Fan Marble Race Season 3 and Marble Racing's Fan Marble Race Season 3.
Like before, the marbles in this scene are just sample marbles (this time, I used the final 15 TWOWers as sample marbles). The marbles you put in (i.e. the contestants) should have a radius of 0.2 metres and have at least collision layers A, B and C enabled.
Also, Marble Racing, since you'll have 20 marbles racing on this, you'll need to make the finishing area 33.33% larger.
Just so you know, the finishing area is blocked off when the alternator is in the "ON" state.
All tools used in this race were made by me.
