I've released the next version of Salzburgring, named v0.4. It includes quite a lot of eye candy already but expect to see more coming...
I've also uploaded a new track, named 'petit' that renders a very famous track in Braselton, GA, USA. It is also v0.4 but has much less 3D stuff in it, but sure it will be the next target of my Blender fun.
You can download them here. Install them the usual way (they should work with both TORCS or Speed Dreams). Please tell me what you think, in the comments or via email.
BTW I have lots of plans for tracks, enough to fill my next 2 years or so :)
