# texture2DArray(slices:named:options:)

Asynchronously creates a 2D texture array by generating it from images.

## Declaration

```swift
@MainActor @preconcurrency static func texture2DArray(slices: [CGImage], named resourceName: String? = nil, options: TextureResource.CreateOptions) async throws -> TextureResource
```

## Parameters

- `slices`: The source images, one per 2D array index. All images need to have the same size and format.
- `resourceName`: A unique name for syncing the texture resource across the network. The name is empty if you don’t include one.
- `options`: A configuration for generating the texture.

## Discussion

Discussion RealityKit creates a MTLTextureType.type2DArray texture with arrayLength == slices.count from an array of images. You can assign the resulting texture to a material you create in Reality Composer Pro that requires a 2D texture array. // Create a 2D array texture from image slices. let texture2DArray = try TextureResource.texture2DArray(     slices: [image0, image1, image2],     options: TextureResource.CreateOptions(semantic: .color))

Task {     // Assign the 2D array texture to a compatible shader graph material parameter.     var material = try await ShaderGraphMaterial(         named: "/Root/Spaceship/MaterialWith2DArray", from: url)

try material.setParameter(         name: "input2DArray", value: .textureResource(texture2DArray)) }
