foggy problem

(Oxygen - o2) #1

hello

i took the fog shader for battery and made customized it so it would have a smaller clipping distance so you cant see as far, but the problem is on the ground the sky disapears for strange reasons but in the air, its fine :confused:

what could cause this?

You might want to post a pic so we can see how the problem looks and your shader so we can see whether you did something wrong.
Apart from that I have posted 2-3 threads on fog and problems with it in this forum and the Q3map2-forum. You possibly will find and answer on this in those ones.

i remember something about the lines that easygen puts into workspawn, could they be problems?

hello

I am not expert at fog, but I don’t think that sky you are using will fog correctly. I have fog in my level, here’s how I did it…
add these key:values to the worldspawn
fogclip:2240
farplanedist:2240
_fog:textures/mp_railgun/fog
and I textured my skybox with textures/mp_railgun/sky

with your fog texture you would want to lower the distances in the worldspawn

ok, il try that
