Just out of curiosity, is it possible to make a semi-transparent texture for a unit? I was just thinking of addaptive camo (ie, the weird cloaking device that the Aston-Martin in the new James Bond movie uses)... Before anyone screams "SCI-FI" and runs in terror I'd like to point out that the U.S. Millitary has been experimenting with this technology and from what i've heard it's very possible to do.
