i edit the UI by extracting the bitmaps from the ui cache.... i wont be doing the HUD for 2 reasons:
1. im pretty sure the hud bitmaps r in every level, not the ui (or in addition to the ui)
2. hmt hasnt supported all the types of bitmaps for extraction like they had promised (among other things *cough* xbox map rebuilding *cough*)
i open each bitmap in photoshop (u need the .dds plugin) and for most of the pics i just ctrl+u, check colorize, and use 120, 60, -30... it gets complicated for the more complex pics. ill prolly do dark red next! expect the dark green release this weekend.
