Now thats interesting stuff; I *had* noticed that FG has lod settings and such but I don't know much about how it works in FG (Although I fully understand the principal). I'll have a go at making another version of the 172 with say, 2d wings, solid windows and less polys in the fusealage. How many levels of LOD (no. of models) do you think would be worthwhile? (I suppose you can first sight individual a/c at 6 miles out.) Cheers. _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
