Playing with TMInfinity
TMInfinity is a popular extension to TrackMania Nations/United Forever that unlocks a lot of map editing features that are not available in the base game. You can play with both TMInterface and TMInfinity, by launching TMInterface and before selecting your game profile, executing load_infinity in the TMInterface console.
This command will try to load TMInfinity first and if it’s not installed, an older version of TMInfinity called TMUnlimiter. If you do not have TMInfinity installed, check out the TMX download page.
Making TMInfinity load by default
You can make TMInfinity always load by default when you’re starting TMInterface, by putting the load_infinity command into your config file.
Note
Some maps created with TMInfinity may not have deterministic physics, which will make TMInterface input scripts not work properly across race restarts. Always ensure that you are running TMInterface with TMInfinity, if the map you are playing on/scripting was created with TMInfinity. Even maps that are playable on the base game may have different physics when TMInfinity is loaded.
