Thanks to philrob for letting me release this conversion.
Aside from the actual conversion I have,
Removed 90% of the trees (they usually don't convert very well) and I added better trees and bushes.
Added 3D grass
Replaced 60% of the buildings with higher polygon buildings and grandstands.
Fixed the cramped pitlane.
Added an invisible bumpy road surface.
Created AI driving line.
Made TV cameras.
Improved textures to better suit AC's lighting.
This tracks looks best in clear conditions between 17:30-18:00 (evenings)
There are 22 pitboxes and 22 places on the starting grid.
PS I haven't made a track map because I don'\t know how to, feel free to make one if you know how.
