Ok since nobody wants to explain .... A high poly count means a lot of details. To lower the polys just remove some of the details because high details on warcraft 3 its not a very good ideea. Get vertex modifier by oinkerwinkle and u will understand.
4k polies? Nice try , but this is a Warcraft 3 downloading site, things are preferable under 1000 polies , maybe even up to 1.5k polies are good, but 4k is just blowing the limit, and more. --donut3.5--
is this converted from wow? or is it from scratch? if its from scratch, then it looks very good except there are too many polies. if its converted from wow then...bah...
