[SOLVED] Missing Textures.

[Demolution]

Well I run Ubuntu Hardy 8.04 and I installed GtkRadiant recently according to Ingar's guide. Everything worked out fine, however when I make a brush, and when I try to caulk it I get these 2 errors. I have only 3 common shaders: noalienbuild, nobuild, and nohumanbuild, if that is of any relevance. Also I have all shaders from the maps that come in the Trem package. Just not caulk. :/
I think I have every path correctly set, and every file in the right place, and yet I get these errors.... I even re-installed Trem to set it to the path in the tutorial. So finally as a last resort I come here seeking for help.

Eh, I got most of these issues fixed so far, except for loading my map into Trem. Feel free to close this topic.
