Hello, I guess they are control lines, all the pink or fuchsia lines, that are kind of nuisance when driving a path, and in some tracks, eg Longford, make them stutter a lot, it would be possible to hide them? Many thanks.
They actually show gaps in the track, which wreak hell with the collision code. You can disable them in the plr file: "Graphics Options":"Gap Check":0 to disable, or hit ctrl-H 3 times. Only relevant to dev build. Edit: Ade beat me to it.
