Advice for world bounds and level design

I am creating a small level that will take place inside a spaceship. I’d like to render the SkyAtmosphere and DirectionalLight elements, but placing my ship actor in the world above the planet’s atmosphere (25000000uu) causes issues with actor collision and movement, and requires me to uncheck world bounds checks in World Settings. I’m guessing this is the incorrect way to handle this - any advice? I was hoping to make use of the amazing atmosphere/lighting capabilities. Using 4.25.

Thanks much for any advice!
