Removing AI Paths

When I'm using a track map with multiple layouts (or any may where I want to make a track) how could I remove AI paths to keep them where I want instead of taking other routes? I've played around in the editor but I can't seem to get anything to work.

 

I have the same problem, I'd like to know how to do it if it's possible

 

Im shoulder deep in a 13 mile mountain road, so its all fresh in my mind. First of all, AI is misrepresented, and very simple to add or remove.

press F11 in game.
in the decal road editor
select the road to remove AI from
Change the drivable variable from 1 to -1
Then go to File: Save.

It will save in your documents/levels folder, if you want to backup, delete or publish it.

Once you get the hang of this, editing roads is easy. Try moving the vector points around and the road width tool. For sections that need to be cut in half to line up with an offshoot road, just delete the unwanted half, and and line the remainder with your planned route. Or you can make a new path under the visible roads and set its render priority variable higher.

If you get carried away and make roads where there are none, you will need to use the terrain paint tool to make road terrain act as such.

The super smooth tool in the terrain editor is very useful for smoothing transitions and new paved areas. Be sure to set the brush width and pressure low enough to be smooth yet manageable.

Now your a level builder
