All official campaign tracks from the 1999 RC car racing game Re-Volt converted to TrackMania with visuals pretty much intact.
TO PLAY THE MAPS, DOWNLOAD THE TEXTURES HERE
Create a Textures folder in Documents/Trackmania2020 and copy all of the files contained in "Textures (create Textures folder in Documents Trackmania2020)" into it.
I unfortunately can't figure out any way (if there is) to keep the alpha channel while using a texture mod, so the textures are going to be a separate download for the foreseeable future.
