Remove the scout's eyes (if it is possible to remove a model's eyes. /clueless) and add goggles (for NF scouts). Pros: No more "OMFG HOW U SEE ME U HAXOR!?" comments from new scouts who think they're completely invisible. New scouts can actually deal some damage before they're found and killed. No silly floating eyes. Cons: Harder to find enemy scouts sabbing friendly buildings. Devs have to do some work / Modelling work Feel free to add more pros/cons.
If you can do it, feel free. But it's not going to get done by the development team, the models are a complete clusterfuck.
Why? When scout is completely invisible you can't see the eyes. See these pictures: http://forums.empiresmod.com/showpost.php?p=321276&postcount=18 And current discussion is more going into the direction to find scout easier to prevent endless search for a scout who is sabotaging the same building over and over.
You can really often actually. It bugs out and you have a pair of floating eyes. This is a bug really, not a suggestion.
