A simple UF1 banger eightfigure track. Ramps on the cross-section to prevent people from going the wrong way around (even by accident )

It can be seen live on the "swain - banger" - server

Are those ramps some kind of add-on to the autocross editor?

Nope - they only exist in Blackwood though

Ah yes I see them now. I don't use blackwood carpark if I make a layout. But I don't understand the point in having different objects for different tracks.

me neither
But i'm not in a position where i can change it.....
