First download the .lyt file from main post,then double click to install it (if your LFS is configured right when installing,if not - save it into lfs\data\layout folder).
Then open LFS and...
1. Click to select Westhill environment
2. Select the "X" beside International configuration to select open configuration
3. Select the right layout
That's how you access the track on single player,no idea if there is a server with it anywhere...
However, I can't get it to work. I installed it just as you said (method 1 worked, but I tried method 2 just in case). I can select the track if I click X on the Westhill International but it doesn't bring the track up. What am I doing wrong?
I have checked the video and while the amount of work put into this is amazing, personally i don't find it good for racing, as some places are either too tight, narrow, dangerous or everything combined.
With that said, it might fit the standards for some of Rony's races.
