.. I think you would do better if you familiarized yourself with magos model editor, mdlvis, and mdlx converter.. As much as 3ds max is useful, sometimes it really derps up on exporting and isn't as reliable as it was before
now magos model editor is really a program that starts and finalizes a model. it can add textures, edit materials, add those glows, even edit animations to a degree, but i would fully encourage using mdlvis instead, as its the tool with much stronger ability to edit model shapes and animation.
mdlx converter you'll need mainly to constantly turn the war3 helper objects into bones, because if anything is attached to them, the model just.. collapses reality
(well not really, but geosets tend to derp up and attach themselves to other models, or the model can crash the game)
you will probably find yourself constantly switching between mdlvis, doing mesh changes, wrapping, rigging animation, and the converter, turning the darn helpers into bones so you don't suffer crashes in both mdlvis or game.. its just the way it is, they're old programs.. but it would be worth it
feel free to ask me questions about these programs and i'll try to answer
