Yes but the shadow-topic was discussed multiple times as there
seem to be some loose ends in the code that allow for manipulation, but all attempts failed utterly. We dragged this through quite some pages on ssm.com some months ago. Stuff is hardcoded.
Another interesting bit of information fo0k found out some weeks ago: Shadow quality differs according to object type. Everything in BF has "bad" resolution (vehicles, weapons, soldiers), but projectiles have kickass-HD-shadows. He noticed that on a thrown grenade. It's easy to verify, because the ExpPack and the landmine have HD shadows too once they are thrown (though their shadow is hardly visible as they are lying directly on the ground

. So if anyone has an idea how to sticky projectiles to PCOs we could have HD vehicle shadows using Apache's "attach"-method...but AFAIK there is no way to do that, as "isSticky" doesn't work anymore.
