Yes ... a 0.5 elevation difference just isn't enough to maintain zbuffer separation from common viewing distances and angles. This gets significantly worse on a card with a 16 bit depth buffer (i.e. voodoo-1,2.3) I believe the code to lift up the runway lights (and ground cover lights) is in tileentry.cxx:prep_ssg_node() Regards, Curt. -- Curtis Olson IVLab / HumanFIRST Program FlightGear Project Twin Cities [EMAIL PROTECTED] [EMAIL PROTECTED] Minnesota http://www.menet.umn.edu/~curt http://www.flightgear.org _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
