Morning all,
I have been doing some testing and have updated a fresh copy from SVN of
openscenegraph-data and the latest SVN.
After running examples.bat I get a blank screen on a lot of the examples...
If I run osgviewer cow.osg it works, but cow.osgt does not, it looks like
its WIP but just to

Hi Martin,
I've had another thought, the old .osg plugin explictly preloads the
core osg class wrappers to retain backwards compatibility with how
they worked bofore, while the new serailizers load an the serializer
dll's on demand. It could be this secondary dll loading that is at
fault.

Hi Martin,
The test.osg you have is missing all the contents of the scene graph
save for the root group. I would suspect that loading of the
serializers is amiss somewhere

Hi Robert,
From your previous emails you reported sucsess, but you weren't
specific in which test this was. So just for cariity what happens
when you do:
osgconv cow.osg test.osgt
osgviewer test.osgt
If this works could you compare the cow.osgt in OpenSceneGraph-Data
and the test.osgt.

Hi Robert,
I can have a go at debugging this if you have no ideas. Clearly changing
all the files in OSG-Data to have Windows line endings is not a solution.
OK, debugging into this, it gets into InputStream::readObjectFields()

Thanks for the testing. It confirms that it isn't a problem specific
problem to Martin's system, and show's that we all haven't done enough
testing of all the different combinations of usage of the new
serializers.
Yeah, well this is the first time I've tried using .osgt files

Hi Window dev's,
I'm currently investigation the problem under Windows with the unix
line endings, which is a bit awkward as I only have a Linux system so
can't test it directly... So will need Windows users to test stuff out
for me.
One thing I'd like to test is whether the addition of the new

Could copy the cow.osgt to cow_76.osgt and then you ammend this files
