Hi Tom, He, he, just for ***FUN*** I tried with 4000 objects...
See the 'crowded' runway on startup - http://geoffair.org/tmp/fgfs-screen-001.png but more spectacular from the air - http://geoffair.org/tmp/fgfs-screen-002.png and had no problems loading ;=)) But you seem to have missed the png texture file from your zip, and maybe that would make a difference? Console output - several times - osgDB ac3d reader: could not find texture "CocoPalmSeedling.png" Did not check the cpu usage, and the total load time was well under a minute... about 30 seconds... If you add that png, I would give it a try with 5000, but the problems does seem to be in your machine at the moment ;=(( HTH. Regards, Geoff.
