I've been playing about with them for a day or so. I can get as far as changing the car type.
What I'd really like to do is be able to use thr Stormrunner, Giga and Junior track in the same ride, to create the ultimate Intamin!
I'm using version 0.65 of the CTR creator, and it's rather limited. I cant seem to be able to use more than one type of track. I know it can be done... I've seen it. Just not sure what I'm doing wrong.
