Ok, I'm working on my first mods. I made one gun, recolored an existing weapon, it works fine. I do the next one, copy/paste a few things together, change the size slightly, and it works fine... if the gun is facing right. If it's facing left, it turns into some weird, random arrangement of lines. It has to be in palliate, I copy/pasted... and there's no code in a simple bmp. So... what causes that?
EDIT: Oh, and when the gun faces to the right, the magenta parts that should make the sprite invisible also make chunks of the actor under it invisible, so you see the sky.
