Sorry if I'm barging in on this issue, but I have two points, which I've partly detailed elsewhere. Firstly, what engine does TORCS use? It's open-source, I've heard, and I've tinkered with it a little, but I don't know much else about it. The problem, I would think, would be more integrating the other SR features like the garage, the moddable cars, etc. which TORCS isn't even close to having. For that matter, it's difficult even getting nice views of the cars you're developing so that you can correct bugs. I haven't found a freecam function, for example.
And on the second point.........if we want to start developing content, particularly cars and mods, what formats should we use? What file types, poly counts, and so one should be used? I've noticed some screenshots of a supposed new SR3 around the internet that seems much more detailed than the beta, so I assume someone is already making content for it. If I want to build something, how should I do it? I'm thinking of making some TORCS cars initially, but then how should I convert those cars for SR3?
