Hazard Water in Portal

Hello, I'd like my portal level to have toxic water covering the floor, but I can't seem to find an tutorials about how to mimic the water from the game. Anyone now the correct parameters? My main problem now is the smoke above the water; My guess is its a func_smokevolume, but I'm not sure on how its set up.

-make all the surfaces tools/nodraw and the top nature/hazard_liquid


Mist on top:

-create an point entity in the middle of your water and set its class name to info_particle_system

-give it the following keyvalues:

Targetname - green_mist_1
start_active - 1
effect_name - water_mist_1024_512
angles - 0 0 0


Making it kill you:

-make a trigger brush that is the same size and shape as your water, possibly a few units shorter so it starts underneath the water

-tie all of them to a trigger_hurt entity and adjust the following keyvalues

damage - 100
damage cap - 100
damage type - CHEMICAL


Removing boxes that get submerged (so your box dropper can respawn it):

-create yet another trigger brush/es in the shape of the water, this time only have them right at the bottom of the water

-tie them all to a trigger_remove entity and in flags uncheck clients (VERY IMPORTANT it will crash if you don't) and check physics objects

Hope this helps.

Great, thanks a lot.
