Entities 220: Lesson 4
Rain and Snow (fx_rain, fx_snow)

Outdoor maps are often complimented by a rain or snow effect.  To create it, draw a brush that encompasses your entire outdoor area - you can use multiple brushes if you want.  Then texture those brushes completely in system/outside.  Then place an fx_rain or fx_snow within each system/outside brush.  That's all there is to it!  Rain!  Snow!

You can also edit the intensity of the rain or snow by adding the key count and a value.  This could be useful if you want a specific area of your map to have extremely heavy rains...

It is also important to note that weather effects do not work in MP.

You will notice when you play that the rain seems very strange without any rain sounds.  I guess that means you need to find an ambient rain mp3 somewhere, now doesn't it? (:
