Ok here is my problem ive added fog to my map and it has black patches that show up threw the fog. Really weird and i dont understand it, Here is my shader.

textures/chronicle_beach/grey_fog
{
qer_editorimage textures/tools/editor_images/qer_fogblack
surfaceparm nonsolid
surfaceparm fog
fogparms ( 0.45 0.45 0.45 ) 2000
}

And here is a screenshot

Ok ive figured out that if i use a brush for my fog it doesnt do this. but if i use "key = fog" "value = textures/chronicle_beach/grey_fog"
it does any ideas why?

did u add the texture to your shaderlist.txt?
that might be the problem, because your radiant might not have added the info to the compiler (info beeing : surfaceparm fog)

also you might want to change
fogparms ( 0.45 0.45 0.45 ) 2000
to
fogparms ( 0.45 0.45 0.45 ) 2000.0
I'm not sure why but in fogs.shader they do that to all fogs

I added to shader text. But i will try adding the .0 see if that changes anything.

Unforchinatly it did not help m8. Any other ideas?

I can't see your picture, mind hosting it on imageshack or something>?

Yes I can see it. I don't think it has to do with the shader of you fog, but with the shader of the texture on the patches or with the patches. If you try to replace them with normal brushes to test, I think they won't show up as black.

I don't know what's causing it though, probably the shader on the patches.

The patches are my terrain and here is my terrain shader. I think you mite have somethen there Lethal banana but im not shur what part of it mite cause it.

maybe (maybe a stupid idea) fogs belong in the fogs map =p

textures/chronicle_beach/grey_fog
=>
textures/fogs/grey_fog

I done understand awesom-o.

Its more likely a VISing and lighting problem.

Does those parts of the landscape have good ilumination from lights?

Fogs were always troublesome, if your fog is added using a brush then this will also cause problems.

try to add the fog to the fogs.shader
all fogs in that shader-file are working :p

His fog is working too, and it doesn't matter if you add it to the fogs.shader or if you make a kit.shader.

It was caused by this part of the shader.

textures/chronicle_beach/terrain_0to1
{
q3map_lightmapsamplesize 32
q3map_material rock
q3map_lightmapmergable
q3map_lightmapaxis z
q3map_texturesize 128 128
q3map_tcGen ivector ( 124 0 0 ) ( 0 252 0 )

but i did not find a fix, so i just made it 1 texture.

Good thing you found what caused it though :)
