things i need for my custom map (detailed!)

[Pootis Engage]

1: Blood Harvest:
Blood Harvest is a great map and i played it too, but one thing i like about the campaign is most importantly, the fog, in the finale, there's a farm house, when you get in there you meet a bunch of things, the radio of course and a kid room and some other rooms, but it had one thing, there was no fog in it, so i tested it and apparently the fog doesn't well... get inside the house but instead stays outside, i would really like this in my custom campaign but we always now that you cant do it, so i would appreciate it if someone tells me it.
2: Dark Carnival
Dark Carnival Is my Favorite Map and the reason is the chubby cheeks gnome :) but others is that the lights and the props look good, and they look really good to be placed in a good place,not only that but i like the Panic Events in the chapters, they motivate you to kill those infected but the design of them is great! even a panic event was a ROLLERCOASTER, so once again i tried to do that, but no hope, and my favorite is the merry-go-round, the sound and the circle path is indeed nice, i like you have to turn it off, now besides that, i want real;y really help with these, and i would be THANKING YOU ALOT!

If you haven’t already, get bspsource to decompile maps, load them up in hammer editor, and see how they do some things.

For the fog, try using the console command “fogui” in-game to tweak the fog parameters as you see fit, take a screenshot of it, then use that screenshot for reference when you punch in your fog numbers
