Morning all,

After running examples.bat I get a blank screen on a lot of the examples...

Hi Paul,
Thanks for the note about the out of data comments. I've updated this
comment and checked it into svn/trunk and the OSG-3.0. The ContextID
is set by the osgViewer::GraphicsWindow intialization, calling
GraphicsContext::createContextID() that manages the unique ID's.
Robert.
On Sun,
Robert,
The unices built fine.
Thanks!

Hi Emmanuel,
I has occurred to me that perhaps your build of the latest OSG is
linking to the mesa driver at runtime rather than the NVidia driver.
The OSG itself just links to libGL.so so should pick up any GL driver
that this linked to, and it could be that on your install of the GL
drivers

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.
The curious thing is that other windows users have been use the new
serializers for a while now without any problems.

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.

That works fine!
Is it the files that are naff that are downloaded from Openscenegraph-data,

I just did a diff on the files, it's the old chestnut of carriage returns at

that make sense?

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

If this works could you compare the cow.osgt in OpenSceneGraph-Data
and the test.osgt.
