How to obtain coherent atmospheric lighting on both sides of the equator?

Hi, it’s me (again)!

As a result of this discussion, I wondered if it was not more appropriate to create a new topic.

I’m very new to Unreal Engine, and I’m ( visibly ) unable to use the atmosphere management tools properly. It’s not, however, for lack of having read the documentation several times.

Does anyone have a suggestion for me to try and get a coherent lighting?

Thank you for your help in advance.
