Setting up hammer to use materials from every Gmod compatible game at once.

Nice bump.

The entities are from the game's fgds. So hl2.fgd, tf.fgd, hl2mp.fgd, ect... All you do is go into hammer>tools>options and where it says game data files add all of them.

The materials/models must be extracted manually into the game's materials and model folders by using gcf scape.
