Fog

I have searched for this and not found anything useful, and also I can't search the forums for just the word 'Fog' because it is too small.

I have a shower room with a drain in the bottom and I want to make it so that the room is foggy around the floor so it is difficult to find the drain cover. Is this possible?

There are two ways to handle fog- with a sky_camera if you are using a 3D skybox, or with an env_fog_controller point entity. Set fog enable to yes, fog blend to yes
(it seems to look a bit better in-game), and specify the other fields-
unless your map is meant to be foggy, then you will want to increase
the fog start and fog end properties by quite a lot, especially in a dry, sunny level- otherwise you will want a low fog start value.

Alrady read that, and already has it in my map... wrong type of fog, that makes it so that you can only see stuff within a certain distance... everything else is shrouded with fog. Well... the env_fog_controller is wrong... and I haven't experimented with 3d Sky boxes yet so I am not sure if that works.

Then I dont think anyone can help you, because fog isnt enabled in
HL2 engine like many other games, you can try massive sprites,
other than that fog stuff its not possible (I dont think)

K... cheers anyway.

Make a brush over the area you want fog in, then tie it to a
func_dustcloud. Then, have fun spending hours tweaking the
parameters until it looks right.

Or lots of steam, perhaps?

make a brush the size of the area you want fog in. give it a nodraw texture and then tie it to func_smokevolume. Accept the default settings and try it out.. works really well.

sorry to dig up an old post but when using func_smokevolume nothing appears in my map, at the moment its just a simple area with 2d skybox and trees and i want fog to trail along the floor so you can hide in it if you duck. any ideas?

I never accepted that post... and it don't work well for me either...
