Is this possible, If i have modelled a track/terrain and city in 3ds can i send straight to racer for use on the cruden hexatech sim we have at my uni?
I take it you are at the University of Hertfordshire?
Yes, you are right in that if you create a track course it can be moved to Racer format pretty easily for you to then drive on!
The racer.nl tutorials are probably a good start, and there is also something called the RCT (Racer Content Tool) which should help you export your 3DS Max tracks to Racer more easily.
Feel free to PM me if you have any specific questions and I can try give you a hand, but as always posting up pictures and explaining problems on the forums is good as you get lots of input and it's also valuable for others to see the answers
