Thanks for the continued interest you guys showed in the track. Well, it made me go back to working on the track to at least get it to the point where I'm not ashamed of it anymore.
First thing that I have done to achieve that is re-do the road textures and add some variety.
I checked what reference material I had on those patches against some clips from the Nationwide race and noticed that they were barely visible. Or to be more accurate: Not visible at all. I still included them however and assumed they faded a lot but are still visible on the track, just not on the video. From the reconstruction photos, the photos you guys sent me I know that some and which parts of the track are newer and should be darker.
Was anyone at the track lately? Have the new parts faded so much already that you can't make them out anymore?
Anyway, it's a start.
