Hi Nico, osgcamera -r Tetra.osg is failing due to issue with clean up of the buffer object pool. I have already tracked down a bug in the clean up of the texture object pool, and found the same problem in the buffer object pool and applied the same fix, but alas still the problem persists so there must be other problems lurking in the clean up of the buffer object code as well.
I'll keep plugging away at it today. Robert. On Wed, Nov 25, 2009 at 8:06 PM, Nico Kruithof <nicokruit...@gmail.com> wrote: > Hi Robert, > Not too much good news I'm afraid.
