Hi Guys, This is sort of what I feared, something that is not easily reproduceable on other setups.
I'm running on a DELL XPS Laptop 2GHz Centrino, 2GB RAM, XP Pro SP2, OSG2.2 VS2005 The original flt file was created in TerraVista, but I trimmed it back in Creator to as few a polygons a possible whilst still failing on my machine Thanks for everyones help and suggestions. I'm just going to have to put my head down and work out whats going wrong my end Cheers Mark >Hi Mark, > >"osgviewer flight1_0.flt" does not crash on my computer. > >- Windows XP >- VS 2005 >- OSG from subversion after 2.2 release >- Envionment variable OSG_OPTIMIZER not set > >Regards >Brede > > >On 10/18/07, Mark Hurry <[EMAIL PROTECTED]> wrote: >> >> >> >> >> Hi Robert/Paul >> >> >> >> In answer to various questions >> >> >> >> Yes osgviewer flight1_0.flt (see attachment) causes the crash.
