Wait, I've seen that before. What's your filter set? I had to remove
showextensions from my filter set because it dumped core. It's not
necessary anyway, just use this chain:
chain trace
{
filterset log
{
filename "bugle.log"
flush yes
}
filterset showerror
filterset trace
}

I would assume so.

No, we're not using those.

You can run it through one of the DVRVolume test programs like
testSimpleVolumeNodeRender.cpp. And raw files usually compress very
nicely using gzip, which the current OpenSG version can load directly.
324 MB is pretty big, what's the resolution of your texture?

No, that's ok then. Let's see if we can get bugle to work...
