Well if we are worried about vertex counts then by using impostors for all execpt the very closest trees you would only have 4 vertices per for the vast majority :-)) Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
