Render material on the inside of a sphere.

I create a sphere that I use for sky and display an image on the inside of it by changing the scale property on the Entity.

Here is how I create a very large sphere and have the material rendered on the inside of it.

                let entity = Entity()
                entity.components.set(ModelComponent(
                    mesh: .generateSphere(radius: 100000),
                    materials: [material]
                ))

                // Ensure the texture image points inward at the viewer.
                entity.scale *= .init(x: -1, y: 1, z: 1)

Almost like you need to reverse the direction of the mesh triangles. I wonder if there’s a convenient way to do that…

Hello,

    var body: some View {
        RealityView { content in
            
            let mesh = MeshResource.generateSphere(radius: 10)
            
            var material = PhysicallyBasedMaterial()
            material.faceCulling = .front
            material.baseColor = .init(tint: .red, texture: nil)
            
            let entity = ModelEntity(mesh: mesh, materials: [material])
            
            content.add(entity)
        }
    }
}
