In many custom mods for StarCraft: Brood War, I have seen custom units present; they even had fully custom overlays, rather than simply unused ones. A good example of this would be the Black Sun Battle Station from Legacy of the Confederation:
How does one go about editing unit graphics to make a custom unit like that? For instance, I would like to make a custom unit that looks like a ZSU-23-4 "Shilka"
I reckon that a reasonably close approximation can be done by replacing a normal Siege Tank's turret with a Covert Ops, adding on a few Goliath autoguns, and maybe a Comsat dish. Except, how does one actually modify unit graphics in such a way? What would I actually need to do to make a unit that looks like a ZSU-23-4?
