# generate(from:named:options:)

Asynchronously generates a texture resource from an in-memory Core
Graphics image.

```
@MainActor @preconcurrency static func generate(from cgImage: CGImage, named resourceName: String? = nil, options: TextureResource.CreateOptions) async throws -> TextureResource
```

## Parameters

`cgImage`

The source image.

`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.

## Return Value

A texture resource.

## Discussion

This method creates a texture resource from an existing
<doc://com.apple.documentation/documentation/CoreGraphics/CGImage> with
specific options. RealityKit uses the resource name to identify
resources, and to match texture resources between networked peers.
Specify a unique name for each texture resource you load or generate.
