Jack_NL, the KCA track seems an interesting one to do, I actually had a look at it before! However at the moment I am concentrating on the Kartrek and my two other tracks -Groningen Airport Eelde Raceway and the Groningen Stadspark Oval + kart track. But I'll keep the KCA track in mind for sure!
I hope not too long (re: waiting), most work is done, it's now in the fine tuning phase, still can't get AI to behave 'cos of the narrow layout of this little track. Am uploading a preview vid now to give you an idea what's already done.
