I ripped Balor from the TFL plugin for Myth II, that I did fine and well, but I wanted to edit the Balor unit, and make him a ghost unit. The second link is as close as I get however, I need some help on him taking 'ghost-like' damage, as of now, arrows and such pass through him and don't do any damage. I looked at the current ghost units and can't see what I've done wrong; is this a problem with TFL based units possibly?
