1.I Use Lumen And HDRIBackDrop for my map,and no other
And the highly reflective sphere has white at the bottom.
2.In Lumen Scene
In the top of HDRIBackDrop
In the bottom of HDRIBackDrop
3.I think Lumen is error
And I use Screen Space,The reflect is right nearby but is wrong in far
And I use Standalone Ray Traced(Deprecated),The reflect is right just reflect skylight,but don’t has cube.
