# texture3D(slices:named:options:) Asynchronously creates a 3D texture by generating it from images. ``` @MainActor @preconcurrency static func texture3D(slices: [CGImage], named resourceName: String? = nil, options: TextureResource.CreateOptions) async throws -> TextureResource ``` ## Parameters `slices` The source images, one per depth index. All images need to be square, and of equal 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 RealityKit creates a texture with `depth == 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 3D texture. ```swift // Create a 3D texture from image slices. let texture3D = try await TextureResource.texture3D( slices: [image0, image1, image2, image3], options: TextureResource.CreateOptions(semantic: .color)) // Assign the 3D texture to a compatible shader graph material parameter. var material = try await ShaderGraphMaterial( named: "/Root/Alien/MaterialWith3DTexture", from: url) try material.setParameter( name: "input3DTexture", value: .textureResource(texture3D)) ``` --- Copyright © 2026 Apple Inc.
