ok, i see some track edits, like at blackwood, and i was wonderin how u put them in and where u get them?

what do you mean "track edits", you cant edit the tracks, just the textures

First you must buy a LFS licence (S1 or S2) and then pressing [SHIFT]+U while being in SP mode opens up a menu, where are the objects, that can be placed on a track.

ohhh kk what's sp mode?

single player

SP = single player
MP = multiplayer
HL = hotlap

Edit: the autox editor can also be used if you run a listen server, ie act as a server but still participate in the game.
