# load(named:in:) Synchronously loads an environment resource from a bundle. ``` @MainActor @preconcurrency static func load(named name: String, in bundle: Bundle? = nil) throws -> EnvironmentResource ``` ## Parameters `name` The image name without the file extension. `bundle` The bundle to search for the resource. Use `nil` to indicate the app’s bundle. ## Return Value The environment resource that loads from the specified bundle. ## Discussion Loading an [`EnvironmentResource`](/documentation/RealityKit/EnvironmentResource) with this method blocks the main actor because it’s synchronous, so only call it from a command-line application. The method can stall a regular app, which makes it visibly hitch, and the system terminates an app if its UI becomes unresponsive. If your image file is at the path `Foo.skybox/Bar.exr` in your Xcode project, use `Bar` for the name parameter. To add an environment resource to your Xcode project, see [`EnvironmentResource`](/documentation/RealityKit/EnvironmentResource). > Important: This function blocks the calling thread while RealityKit loads the requested resource. --- Copyright © 2026 Apple Inc.
