The Game Database File (GDB) contains general information about the track.

Atmospherics

This is a new section which allows us to configure the atmosphere of the track, scaling how the Haze, Air Pollution and just how bright the night sky gets. You can adjust these values in real time in the Time rollout in ModDev and SceneViewer. However you need to save their values manually.

AirPollution (0.0 to 1.0): This configures how "dirty" the air is. It defaults to 0.25. At 0, it is much whiter and cleaner, at 1.0 it is much more red.
NightLightPollution (0.01 to 30.0): This is a scalar for how much pollution there is at night. 1.0 is considered a good value for most venues, however if your track is very urban or very rural then you may wish to adjust this up / down. We would recommend that a really busy metropolitan area might have something around 15 - 20 for this.
HazeBaseScale (0.01 to 10.0): This is a scalar for how much haze there is applied to terrain and sky on a clear day. Be sure to check to see how it blends with your backgrounds and more.
HazeCloudyScale (0.01 to 10.0): This is a scalar for extra haze added on top as the scene becomes more cloudy. Typically this is a small addition and allows us to make the horizon blend in better with the overall conditions.
HazeStormScale (0.01 to 10.0): We can configure how much extra haze is added as it starts raining hard. By default the visibility comes in a lot as the rain starts to come down.
HazeDawnScale (0.01 to 10.0): Finally we can adjust how much haze we have at Dawn and Dusk. This can make for some quite atmospheric conditions as the sunrises.

Parameters

Settings Info

Be sure to set a unique Settings folder for each layout.

Loose Object Data

Any object that is collidable and movable needs to have it's instance name setup here in order to have accurate collision effects.

DRS zones

Following data determines Formula 1 - style Drag Reduction System (DRS) areas around the track.

  RearFlapZone               // zones for using rear flaps in race sessions
  {
    MinimumCrossings=2       // how many times you must cross the detection under green before it is allowed
    TimeThreshold=1.0        // seconds behind another vehicle for it to be allowed
