Hi Björn,

Sorry to hear that you have .osgb's that are failing.

I can have a look into it.  It could be a simple regression but also
might a more awkward issue to resolve, there is chance that there is
incompatibility that is not straight forward to resolve - for instance
if there was a bug in the original writer/file format that has been
fixed.  If the later then it may be a case of writing out the file to
a .osgt, .osg or .ive and then reloading and writing back out as a
.osgb.  For testing purposes it may be useful to do this.

What version of the OSG where these files generated with?

Just send me a link to the files directly I can have a look myself.
