High-Res skins?

Well, i've made a few 512x512 skins, but they like wont work! (its not my editing too, i tried to simply resize one and import and it crashed)

is there some sort of .mdl edit or a new unwrap i need?

have you tried viewing it using the Wc3 viewer

-make sure it is exactly 512 by 512, it can't be off at all
-double check the alpha channel to make sure everything is in order

hmm mountainking must not be high-resable. Shadowhunter worked fine!
