Ahh dammit. Yeah give me a second to download and reupload. I must not have checked the box "make 0 transparent" in Image2Tex.
Actually, whether I did or didn't have it originally checked doesn't matter. The way FF7 handles transparency is if it's not exactly color 0, it still shows up. So basically, someone needs to go around the entire outline of the flames painting it completely black. It'll probably make the flames look less cool, but that's how it's gotta be AFAIK
