# swizzle

Channel swizzle to use when RealityKit reads or samples from the texture.

## Declaration

```swift
var swizzle: MTLTextureSwizzleChannels
```

## Discussion

Discussion The default value performs no swizzle, sampling red from the texture’s red channel, green from the texture’s green channel, blue from the texture’s blue channel, and alpha from the texture’s alpha channel.
