Jp, Thanks for the suggestion. I'll give it a try.
Thinking that it might be a video card limitation (texture memory), I tried building the same content on a more capable video card (Nvidia 9800 GTX) and I'm still having the problem of having the osgdem threads dying out. I'm suspecting that VPB is having trouble with the large tif files and the number of them. I have 10,271 tif files in a single directory where each tif file is ~30MB in size. If I pare down the number of files to just a few, it builds fine. When I throw the full gamut of tif files at it, VPB chokes. Apparently there's some sort of limitation here to what it can handle. I'll continue to investigate and post my findings... -Shayne -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of J.P.

Hi, you can check in the tasks folder to see exactly the osgdem command(s) that would be executed by vpb. Try execute one of these manually and see if it does not report any useful errors. jp On 21/10/10 20:31, Tueller, Shayne R Civ USAF AFMC 519 SMXS/MXDEC wrote: > All, > > I'm seeing some issues with VPB when attempting to build a very large > database.
