I'm stuck, I cannot find this shader and my map won't compile.
anyone got any ideas as im lost.
shader type world/ba not found

I'm going to answer my own question to show how easy it is to screw up or to show how thick some peeps can be.
Have you made any custom pics I wonder.
DOH, what a fool I am, YES, ba1 and ba2

I removed them from textures when I decided they never worked in the map and forgot about them because I take so long to compile.
