The scene capture cube does not function as a camera, but as a host to capture a cube map that can be used for ambient lighting. Primarily I used the capture cube to create a cube render target, turn that into a static texture, and then add that cubemap to the skylight.
The default value for roughness is 0.6, which means you won’t have intense reflections showing in your capture cube. I am not getting the same results you are, and my test case was very straight forward.
Thanks,
