Kris Vickers has been working on his BTB scratch made track Croft for around a year, and after a very successful beta test a little over a month ago here at RD, he has released the track publicly as version 0.85, only for rFactor. The video shows version 0.82, but very little has changed visually.
Kris has further layouts and new height data planned for future releases.
Kris is still looking for constructive feedback and his Croft thread can be found here
