The tools I use for modding are Milkshape 3D, Ultimate Unwrap 3D, Adobe Photoshop CS2, Valve Hammer Editor v3.5, Nem's batch compiler with zhlt compile tools, Wally Game Texture Editor, Jed's Half-Life model viewer and Sprite Explorer. I don't have much stuff to show right now, but I hope you guys will enjoy the things that I show in the future.
Here it is partially skinned. The receiver and other parts unwrapped onto the same map are nearing completion. Once they're complete, it'll be time to move onto the rest. Which is a lot :(
