Ghosting Mod

Ghosting mod is mod that I have been working on that can display a past run that you did, in game. Think of playing back a demo, but instead of watching the demo in first-person, the playback applies to a model in your game. This is very effective for racing against other people, as there is an option for online, realtime racing as well! Make sure to read the README.txt in the folder for instructions on how to set up and use the mod! (external link)
