I know this is a bit of an older post but I've just started adding the mettle bar into my skin and I'm wondering if you've figured out the mettle full display?
Is it possible they are using a sprite sheet that's animated by the engine since you can't have an animated TGA. What's more likely is it's some compilation of TGA files making the animation.
What I can't figure out how to do is either view the dat files, or which one to look into for this info.
Has anyone ever been able to unpack the various pak files? I can view a bit of info in a hex editor but I can't seem to figure out how to uncompress them.
