I've occasionally edited some armor skins. In doing so, I found that if I saved a PNG image as RGB format, then converted it into a BLP, it caused the texture to not appear in-game. The only way to get my textures to work was to save them in Indexed format, but unfortunately this tends to look pretty crappy, and I'd like my textures to look less jagged.
Can someone tell me how I'm to get my textures saved and working with an RGB format, or at least one that's smoother than Indexed?
