Update: Track has been rescaled so it does not feel too short or too difficult to drive on when racing on higher difficulties. Sweet Ride music files are also included so you don't need to download track one for them. Mod link: gamebanana.com/mods/518652
I was working on the third track but the main problem was vertex colors. Basically most of the track looks black and I'm trying to fix it. As for the 5 racers, I updated Vanellope's car model to the one from the game, but never saw the need for the others besides wanting to give Vanellope a decent car model.
