I took this shader directly from another fog shader, which I tested in game, and works. However when I try mine, it shows notex on the fog brush, and the console says "trying seafog.TGA". The other for shader I took it from (q3wcp16), does not have a "seafog.tga" in the textures folder for that map. Am I missing something here? Why doesn't this work? I tried renaming "seafog" to other words and I get the same result.
I could just use q3wcp16's fog shader, but the problem is I need a different distance to opaque than that one uses.
@Bacon: First, did you include your shader file to shaderlist.txt? If so, you should see a white border arond the shader image (in your case the missing one) - this means it is a shader and compiler will consider it as shader and take its parameters.
Second: If you want to have the texture with FOG written on the surface in the editor, you must take the existing one (in your case the blue one) or make one yourself. For using default you have to specify qer_editorimage general directive in the shader, if you want to make your own editor texture, best is to name it like the shader (unless you have much more fog shaders that have similar settings)...
