Sky Atmosphere material rendering Black

Hey everyone. So I am trying to recreate a simple sky atmosphere material as shown in this video Exploring the depths of the new Sky & Atmosphere system | Unreal Engine - YouTube . However, upon applying the material to a sphere, it only ever renders as Black.

Im not sure what I am doing incorrectly. I have a directional light and a skylight in the scene. The material has “is sky” checked and is set up as opaque and unlit.

Insight is appreciated as resources on this seem to be limited

Do you have a directional light in the scene that has Atmosphere Sunlight enabled?

I do, yes

Post your material
