Adding goeset

Level 17
Nov 21, 2012
I have item sword model by Kitabatake. It is very hard to select or right-click it in game. So I tryed to add geoset taken from original war3 "LillyPad" model.
In Magos -> Material Manager-->Material Layer I used Textures/Star7b.blp, Filter mode: Additive, Unshaded and TwoSided ticked. It looks fine in Magos, however in game and in war3 editor this added goeset is somewhere else but not with sword model together, also easier select is not solved. How to add properly new geoset for easier selection? Or maybe there is other way to make model easy selectable?
