Lightmap in scene A causes lighting in scene B to look weird, even when scene A is not loaded.

I have two scenes. Scene A has baked global illumination. Scene B does not.

Scene B

I load scene A, then load scene B additively.

Scene B when Scene A has lightmap baked,

Scene B when Scene A has lightmap cleared.

None of my scene B renderers have a lightmap assigned (obviously).

If I load scene B without loading scene A, the result is still the same…
It’s very weird that a scene that isn’t even loaded affects a loaded scene.

I really only want to use lightmaps for scene A and not for scene B.
And I also want to sometimes have both scenes loaded at the same time, additively.
Help?

[Edit]
For more context, scene A has dozens of baked lights. Scene B has zero baked lights.
Scene B uses a realtime directional light for lighting. This light keeps moving and rotating.

Okay, nevermind. I’m an idiot. This is just a case of PEBKAC.

The solution is to create two Lighting Settings assets.
One for no baked lights, the other for baked lights.

Scene A gets the Lighting Settings for baked lights.
Scene B gets the Lighting Settings for no baked lights.
