curious, that 4 barred ones sure familiar, looks alot like the 25% health bar I made long ago, never released it though, hmmm. maybe its just coincidence
I really like these, they are nice.
If they don't work in peoples maps don't fret its not hard to just re-save it over top a fresh export of the normal health bar texture, I found sometimes health bar textures seem to be finicky and annoying to get right when saving them, and converting them too. they have a different way of using the alpha channel some how, and if you have a pixel of alpha on one of your textures edges, specifically the outer right top corner edge, it causes some very odd issues. the solution is to have no pixels on the very out side edge of the health bars texture, in the alpha channel, some times black looking pixels have a tiny bit of white in them, its barely noticeable, a pretty easy fix.
