D4U.ndeadyea i need it for a map but i already have the textures the only problem is an error when converting the m2 into mdx file.
you don't need to remove unused geosets it's not that big problem if the file is big
I think the problem you have with the m2 to mdx can be solved pretty easily. Get mdlvis to convert the m2 to .mdl, then use Yobgul's File Converter (Called War3 File Converter on this site i think) to convert .mdl to .mdx.
i tried out nearly everything with mdlvis and the mdx to mdl converter. i converted m2 to mdl and then tried to convert to mdx with Yobgul's File Converter and there was an error which said there were any symobls expected in line 1...
i tried to convert directly from m2 to mdx and the model had no texture in the game and was invisible. i tried to convert to mdl and convert to mdl in mdlvis and the model was invisible...
