I don't want to add a portrait to a unit, which doesn't have one (yet).
I want to have a unit with portrait, but NO MODEL.
I tried to create a blank model. I called it "NoLich.mdl", then I extracted the Lich's portrait, and I imported it into my map, calling it "NoLich_portrait.mdl".
Thought that's gonna work, but it didn't... The portrait window is empty =/
