# cube(slices:named:options:)

Asynchronously creates a cube texture resource from face images.

## Declaration

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

## Parameters

- `slices`: The source images for each cube face in [+X, -X, +Y, -Y, +Z, -Z] order. All images need to be square, and of equal size.
- `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 Provide the cube faces in the following order: [+X, -X, +Y, -Y, +Z, -Z].  |  |  |  |  |  Use the resulting texture to create an EnvironmentResource, or assign it to a material in Reality Composer Pro that requires a cube texture type. // Create a cube texture from image slices. let cube = try await TextureResource.cube(     slices: [posXImage, negXImage, posYImage, negYImage, posZImage, negZImage],     options: TextureResource.CreateOptions(semantic: .hdrColor) )

// Create an environment resource from the cube texture. let environment = try await EnvironmentResource(     cube: cube,     options: EnvironmentResource.CreateOptions() )

await MainActor.run {     // Assign the environment to an image-based light component.     let lightEntity = Entity()     lightEntity.components.set(ImageBasedLightComponent(         source: .single(environment)))     ... }
