Autobahn 0.3

• new terrain with basic texturing
• improved pitlane, pit entry and exit
• better and more optimized AI line
• improved texture shaders
• basic multilayer texture for the road
• reduced lane marker height
• added objects to mark the two hairpin corners

A little update before the Porsches arrive.
Nothing major, still no real textures and objects but a bit of polishing.

changes:

• better terrain (no proper texture yet)
• pits added (very basic atm, will change)
• AI now always overtakes on the left and never goes over the solid lines
• road markings are now seperate objects, making them much sharper in the distance
• added sound and vibration when driving over road markings
• slight improvement to road texture
• added object Notrufsäule (no proper texture yet)

- added track map (thanks to Deswribilator)
- changed preview image
