David, if you only use the texture space within (0,0) (1,0) (0.5,1) and use a single triangle for the billboard, does it save a vertex ? That might let you use a lot more trees, even though it won't help other stuff such as buildings. _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
