How do you remove sea level effects?

Thanks for the extra info,

I’ve never seen anything like that before, so I’m curious about how to replicate it. (I doubt the custom skybox is related)

1. Create a new ‘Blank’ level
2. Add prefab ‘Colossal Coliseum’ ontop of grid (this would place prefab at grid plane height)
3. Delete the 4 ‘grid planes’
4. Launch session (this only appears in-game on medium or higher settings)

Still no luck:

If you search your outliner for ‘water’ or ‘lake’ do you see anything?
