New Game Update

So I Decided to make a racing game. I want the game to be very customizable so one of the first things I've implemented is a alpha of the vehicle customization. I've made it so you can change the color of the tire and the car itself and change what type of tire the car has. You can also change the material of the car, even to a custom image. You can choose the custom option and put in a url of an image and the game will put that on the car. In the future when the actual cars are implemented I plan on uploading the Imagemap of the vehicles so people can completely create custom skins for the cars. as of now its really just about the mechanics of being able to do so. most assets are placeholders as of now while I create the necessary scripts and assets to properly make a game that works. I would like the game to be multiplayer but I'm not sure how to do so yet.
