it looks like its just a sprite, look inside anzio.bsp ie.rn

yeah i thought back when i did some dod mapping (pre-steam betas) there was an env_fog entity that would create fog in maps.. but like many other useful things, it seems they removed it at some point..nntho they probably removed it cause you had to run in opengl for the fog to work, so ppl running in d3d wouldnt see any fog

Check out dod_brume. Its loaded with fog.

I remember a map that declared that the coastal fog was rolling in and the screen went grey even in sniper some how for a couple of minutes (Not a plugin). It was an effect I have'nt seen before in any other map, can anyone else remember it for this guy? It was a large but bare snow map. I have too many maps to go through now.
