Hi Joakim,
I'm afraid I can't delve too deep in users problems, I'm very busy. I
have time to point people in roughly the right direction, but if the
route is uncharted by me then I'm afraid I can't much in the way of
quick wisdom.
Robert.

Well I have now made a small test app. dbpagerviewer.cpp. It behaves very
strange. Have I made a mistake in my code, or is it a bug in osg?
See the two attached diagrams. The diagrams show the framerate and the
number of texture objects loaded into video memory. osgviewer.png shows
how it looks like when loading a model with 126 different textures with
osgViewer.exe. No mystery here.
The dbpager.png diagram, illustrates what happens when I load the same
model with the dbpagerviewer test app. When the model appears in the
viewer (at the red vertical line) it seems that it is loaded again, and
again, and so on.
