# init(contents:)

Creates a new material property object with the specified contents.

## Declaration

```swift
convenience init(contents: Any)
```

## Parameters

- `contents`: The visual contents of the material property—a color, image, or source of animated content. For details, see the discussion of the doc://com.apple.scenekit/documentation/SceneKit/SCNMaterialProperty/contents property.

## Return Value

Return Value A new material property object.

## Discussion

Discussion Newly created SCNMaterial objects contain SCNMaterialProperty instances for all of their visual properties. To change a material’s visual properties, you modify those instances rather than creating new material property objects. You create new SCNMaterialProperty instances to provide textures for use with custom GLSL shaders—for details, see SCNShadable.
