Ok , so iv been lately using the BLP converter to modify textures and figured out that its annoying when you cant model edit due to to many textures for it all to fit together into 1 texture file that you could possibly need. so im not sure anyone knows about this but i think i found a way to conjoin texture files , its a little glitchy and i havent tested it yet but what if you were to use paint (or whatever tool you use to edit textures) and you put multiple textures in 1 file , save up that file under a name and use it , the new conjoined-texture file to make it like 1 file instead of 5.
once again idk if anyone posted this or knows about this but its just maybe a step forward past blizzards boundries?
who knows!
