making fog

Hey all!

I was wondering how you make fog in HL it looks like the underwater blur only with no water. I saw it used in Todesogist 2 how do you do that? huh huh huh

use spirit- http://spirit.valve-erc.com. On the particulars of it, I'm not too sure, but there will be many people to answer your question fully.

You can try using A LOT of sprites, such as smoke sprite (with different rates), but when I mean a lot I really mean like one sprite for every 100-200 units, to give it a real feel, other than that there is no real way to make fog in HL, Execpt for spirit, like crono said.

The only time I think you can get fog is underwater. Meaning a func_water entity. Other than that, if you want fog in small areas (say like tear gas in a room) use some smoke sprites. They look good.

You can check out my Catalyst map, I had a "toxin" room where green gas came out. Kinda s**tty to my standards now, lol, but you see what it looks like.

Not that im calling you wrong, but I think it was func_illusionary, if you set the contents to volumetic light instead of empty, wich is what half dude could use, but your still underwater.

but you still drown after a while...

Why didn't they just include an entity that's exactly the same as a func_water, but that doesn't let you swim/drown? Surely fog like that would have been a nice feature to include in the game, and shouldn't have been too hard to implement considering it's just an existing entity with less properties...

It probably just never crossed their minds. Back then though, fogging was seen as a cheap way of getting around the limitations of your engine so that may have had something to do with it.

I suppose I have Lep to thank for the blue :smile:
(taking that I never even marked my comment as a solution)

You could try adding many blue func_illusionaries.
