# groundColor

The color of the simulated ground.

## Declaration

```swift
var groundColor: CGColor? { get set }
```

## Discussion

Discussion By default, this property’s value is nil, causing Model I/O to render an infinite sky above and below. If you set this property to a color, Model I/O renders a solid color for all areas of the cube texture below the level specified in the horizonElevation property.
