no fog in buildings

[Mercenary]

I'm trying to do this tutorial

http://www.planetquake.com/6thfloor/tutorials/multivolume_fog.htm

I'm stuck at the part where it says "Unzip fogcaulk.zip..." I can't find a good link to this file. Does anyone know what the shader code is for "fogcaulk"?

just use caulk_nonsolid
