Hi Till,
I don't know all the nuances of the OSG branch and OSG usage, but originally
the common material library textures were all loaded at start time so they'd
be available at any time and not hit the fps like they would if they needed
to be loaded on demand. Then we bumped up the reference count by one so
they would never be deleted from the system.
Regards,
Curt.
