Hi!
I've just downloaded Stunt Rally and I must say it is a lot of fun. While playing it, I really thought about how it would be great to have tracks splitting in several branches and then joining back together. I didn't see any way to achieve this in the track editor and I even saw it had been submitted as an issue on the Google Code website (issue 235 : https://code.google.com/p/vdrift-ogre/issues/detail?id=235).
In summary, I was wondering about the state of the development process regarding road splitting. I would also gladly contribute towards its implementation if such help is welcome, as I have some experience with C++ programming.
