Fixed background in visonOS

I successfully changed a picture to the background in ImmersiveSpace in a full state with the following code.

import RealityKit

struct MainBackground: View {
    var body: some View {
        RealityView { content in
            guard let resource = try? await TextureResource(named: "Image_Name") else {
                fatalError("Error.")
            }
            
            var material = UnlitMaterial()
            material.color = .init(texture: .init(resource))
            let entity = Entity()
            entity.components.set(ModelComponent(
                mesh: .generateSphere(radius: 1000),
                materials: [material]
            ))

            entity.scale *= .init(x: -1, y: 1, z: 1)

            content.add(entity)
        }
    }
}

However, when running, I found that when the user moves, the background is not fixed, but follows the user's movement, which I feel unrealistic. How to fix the background in the place where it first appears, and give the user a kind of movement that is really like walking in the real world, instead of letting the background follow the user.

Hello,

Are you sure that it's following the user? It may just appear that way because it is so large (1000 meter radius). Try making it a lot smaller (try a 1 meter radius), and then see if it behaves as you'd expect.
