Doom GFX is not BMP. WinTex automatically converts between the two, but they are not the same thing.

Explain a bit please? Not sure if I understand...

Doom does not use .bmp files as graphics. XWE, WinTex and other editors automatically convert from .bmp to the raw format that Doom uses for graphics. ZDoom's developers decided not to add support for actual bmp graphics, because that was unnecessarily bloat filesize for no gain.

Oh really? So, I suppose that that means that WinTex can only convert from bmps, converting to the raw file. I suppose that makes sense. And with ZDoom though, other formats can be used, like pngs, too, do something, or make it easier I suppose. I think someone said that pngs are palette removing which I think would thus make the graphic work with Doom, Heretic, Hexen, Strife, ect.... Right?

Yes. The graphic formats used by Doom are actually well known and documented on the Doom wiki:
http://www.doomwiki.org/wiki/Picture_format
http://www.doomwiki.org/wiki/Flat


More precisely, PNG files can be paletted or in true color (24-bit RGB, or 32-bit RGBA), but a paletted PNG file contains its own palette instead of being dependent on an external palette like Doom's native graphic formats.

Then ZDoom is able to match the colors to their closest approximation in the palette it uses, so you don't have to do the conversion yourself. And GZDoom is free from the palette entirely.

Alright thanks for the info.

Anyways, i have updated file with what was before suggested: Png and variations. There are now two dead Corvus's, one like before, and now one who is green and flipped horizontilly.

Hope that works.

EDIT: Changed Info in first post. Summon DeadCorvus for original or DeadCorvus2 for a flipped green varient. Also changed Rave to Raven

Alright, changed the first info again. Palette is Heretic, or PNG I suppose.

Hope that is good.

Fine, there you go
