How do I make snow/rain in Hammer Editor (EP2)

Hey guys, Im making a Spa map where its steamy water and stuff with snow around you, I tried env_rain/snow and Hammer doesnt have it for EP2 so, how do you do it?

its func_precipitation


Just dont set density to 100.
99 is fine, but 100 can cause vertex buffer(HURRR) overflows

I made a nice map, looks awesome!
Its a Spa In a coffee cup! in the middle of a snowy mountain/tundra/forest kinda cool

Nice. Pictures?

It has to do with the size… 100 density at 1024^2 may crash but so will 99 @ 1048^2.

I just made up the numbers, their no where close to accurate but it’s the idea behind it.
