Did skyboxes change?

[Tupperwits]

I remember looking around a decompiled arena_watchtower ages ago and all the trees and the radio tower were in the skybox and then appeared physically rather than just on the sky. I had an idea using this method for a map but when I looked again recently all the models are in the main area.

Did I make the old version up? Did the way skyboxes change? Is there a way to do this?

You're imagining things. Arena_watchtower has never had a 3D skybox beyond the raido mast itself.
