just not shure adding fog to a map for multi player will be any good

• Agree x 1

The fog only works in OpenGl.

since this is in cs 1.6 threads it was understood , let me know how your project works out good luck

Use the env_fog entity..

Ok, no problem, you should put the env _ fog entity, somewhere on the map (works as light _ environment), and you put with the following values

Tab "Class Information"

Clase: env_fog

Atributtes:

Fog density (0.01 > value> 0): put 0.0005

This is a bit dense fog, but acceptable. More density? try increasing the value: 0.001

Fog color (R G B): here choose a color (preferably dark gray color or 128 128 128)

Tab "Attributes":

• Start active (you mark this box allways)

I hope you have been helpful.
