Question about rain

It's a particle system. particle_rain_001, IIRC.

If you want it to collide and kill on brush surfaces, particle_rain_001_collision

info_particle_system

Name: env_rain_001
Start Active?: Yes
Flag as weather: Yes

EDIT: It has a radius of 512 and a height of 1024, so be sure that each system is not any closer than 700 units to each other.

The way I've handled it in the past is by creating a 1024x1024x1024 cylinder, placing an info_particle_system with the proper info at the top dead-center, and then shift-dragging it to where I need. In the overhead x/y view, you can see these cylinders and where they overlap.

Also, it'll go through buildings (unless you're using that collision rain, but it's very intensive on systems), so be sure to place it mainly outside.

you can also use func_precipitation on a trigger box, and just make a box where you want the rain.

Of course. Duh.
But I am at work, so I couldn't look it up.

By the way, what does "flag as weather" do? Because on sawmill the rain isn't "flagged as weather" and I haven't found or seen any difference in the particle system's function.

It's in the advanced options to toggle weather on/off. If a player wants it off (due to low FPS or whatever), it won't run. Valve's weather particles are hard-coded as weather, and the flag as... option is mainly for custom particles.

It still can't hurt to set it, though.

Ahhh.

So you could mark some rain as weather, and others as not. Then those with "weather" turned off would still get rain, but only in the important areas (the filler systems would be turned off).
