Anywho...although hl2:dm isnt played as much, its materials are used by a mod of it known as garrysmod. Basically I have no skill or knowledge in making mathacks as I am horrid with computers. Mathacks are basically the process of taking your original materials, and making them slightly transparent. There use to be one availiable but its gone now. Not to mention material hacks are a lot easier and safer to use then coded hacks if you plan to wallhack. If possible could someone take hl2 materials and edit them so their slightly transparent? Its been done for css but not for hl2, I'm talking about simply only adding transparency to default hl2 materials.
