on the tool bar (file,edit,view, ect) go to "module" a drop down menu will appear, select import manager. In the import manager right click on the blank space and you will get options select import file(s). find the model file or what ever it is and then change the path (if you downloaded off this site then it will tell you the path at the download page). Put the model on the specified unit then place on editor. you wont see it yet you have to save, then close editor. reopen editor and map. you should see the model
hope that helps you
anyone know how to put a glow on a non-hero unit?
