# tWrapMode

The coordinate wrapping mode for texture t-coordinates.

```
var tWrapMode: MDLMaterialTextureWrapMode { get set }
```

## Discussion

Texture coordinates canonically range from `0.0` to `1.0`; wrap mode determines the behavior for samples from outside that range. For details, see [`MDLMaterialTextureWrapMode`](/documentation/ModelIO/MDLMaterialTextureWrapMode).

The t-coordinate is the second value in a set of texture coordinates, used with two- and three-dimensional textures.
