I have a problem with my shader file for my custom textures.
When i put this shader file in my final pk3 file the textures doesn't appear in the game but when i use a pk3 file with only the shader file inside then he can find the textures.
Here is a picture from my shader file: http://www.dodstudios.net/uploads/uploads/o.jpg
I checked the directory's and i can't find it. You can see that he can only find one textures at the wrong place because that texture is for the interior for that little house. http://www.dodstudios.net/uploads/uploads/shot0162.jpg
i'm not really sure, what your problem is, especially your last post was a little confusing for me.
But I saw in the shader C_1.jpg. Try to write C_1.tga, but don't rename the file itself.
