[WIP] Sci-Fi flying fortress in Gmod (Ace Combat inspired)

So, I had this idea to make a huge flying carrier that allows players to walk through.
There’s no interior nor wings so far. I was currently experimenting with heat distortion
thanks to env_smokestack entities, emitting refraction-rendered normalmap particles
and it seems to work out pretty realistic compared to the env_steam entities.
THIS IS A WORK IN PROGRESS. I was almost certain there was a WIP tag, but didn’t
find it in the list.

I appreciate help and suggestions to make it look even better.
