## Fields

| Field | Type | Required | Default | Allowed values | Description |
|---|---|---|---|---|---|
| `mode` | `FogMode` | no |  | `height`, `exponential`, `linear` | height (default): exponential fog that thins with height (`heightFalloff`). exponential: the same with no falloff, 1 - e^(-density * d) past `startDistanceM`. linear: none at `startDistanceM`, full at `endDistanceM`. |
| `color` | `string` | no | `#CCD9FF` |  | Hex colour of a fully fogged surface as it shows on screen, the spelling skyColor uses: "#8FC0F0". Default "#CCD9FF", a light grey-blue. Match it to a color sky for a fogged horizon. |
| `density` | `number` | no | `0` |  | height and exponential: extinction per metre at the base height, 0..1. Default 0.02. |
| `heightFalloff` | `number` | no | `0` |  | height only: how fast density thins with height, per metre, 0.001..10. Default 0.2. |
| `baseHeightM` | `number` | no | `0` |  | height only: the height, in metres, where density is `density`. Default 0. |
| `startDistanceM` | `number` | no | `0` |  | Metres from the camera where fog begins, 0 or more. Default 0. |
| `endDistanceM` | `number` | no | `100` |  | linear only: metres where fog is total, more than `startDistanceM`. Default 100. |
| `maxOpacity` | `number` | no | `1` |  | Cap on the fog's cover, 0..1. Default 1. |
| `hd` | `SceneFogHd` | no |  |  | HD-only fog fields; the standard renderer ignores them. |
