The Gravel Traps now correctly use the Kunos sand surface preset. I had originally forgotten to make the Gravel Traps a separate mesh. (Grass still uses the same Kunos preset as before).
The trees are no longer symmetrical.
Softened the tree shadows.
Added the North Layout.
Added the Motorcycle Grand Prix Layout.
Added the circuit corner names for each layout in the "Track Description" app.
Fixed the issue with CSP "Advanced Culling" causing issues when going under the bridge.
Fixed the issue with CSP "Hide Spectators" making meshes invisible.
