[quote="Firebrand":31bevxjp]Patches can be whatever format Vavoom supports (BMP, PCX, JPG, TGA, etc.), but all patches require a corresponding texture defined, the game only recognizes textures defined inside the TEXTUREx lumps. AFAIK, there's no other way of doing this.
No, there is a way of simply putting a graphic into "textures" folder (possibly inside "textures.pk3") and engine will treat these images as textures.
Come on, Firebrand, I don't believe you did not know that.
