I think there is something wrong with my Radiant Program...I load the textures from one of the choices, and all "normal" textures come up with a nice preview of what they look like. But such textures as skies, caulk, clip, to name a few don't show a box with "Caulk" written in it, etc, they just have the black and blue checkered picture. Then in the game, for example, my "invisible" brush with the texture "clip" applied just shows the error(?) texture of the gray and white grid. Anyone know how to fix this? Thanks for your help.
