I want to know which programs i need to learn in order to make good maps for Source engine games.
i know Hammer is the Map editor, but what do i use for textures (for the walls/floors etc.) and what do i use for making props (items in-game etc)? Blender and Photoshop are all that's needed to make a quality map?.. let's say for example like the new DE_SEASON, which i think artisticly and comptetivly is very nice. which tools do i need to learn to make a map like that?
