# hidden

A Boolean value indicating whether this object should be used in rendering.

## Declaration

```swift
var hidden: Bool { get set }
```

## Discussion

Discussion Model I/O is not a renderer, so this property is purely informational. Renderers using assets imported using Model I/O can use this property to determine whether to include meshes in a rendered scene, apply lighting from light sources, and so on.
