where from i can find texture in coduo radiant? in cod radiant they show up in "texture", but not on coduo radiant.

or do i have jsut a wrong program? because everybody are talking something about other program that isn't coduo radiant?

go to the tutorial section. There you will find a tutorial called setting up the editor or somthin like that. It gives step by step explanations on how to set up the editor so you have all the models and textures provided with the game.
