Hi Sunil,
Just to be clear, you also need to specify a two-sided light model to
make OpenGL apply both front and back materials.
The osg::LightModel class allows this.

Hi Brad,
The plugins are designed to be entirely encapsulated within themselves
and not to export any symbols, save for any C function entry points
for enabling static linking of plugins. This decoupled approach does
mean that you don't have any public interface to access internals

I don't know if it is possible from the command line. You could
osgconvert the files that are in odd orientations.
Programmatically, just don't use the same osgDB::Options object in the
next read.

Hi Brad,
if the only thing you want is to pass paramters / objects to the plugin,
so it sets up its stuff accordingly you can use
ReaderWriter::Options::setPluginData and extend the DirectoShow-Plugin
to use these plugin-data if available.
So you can feed you directshow-pin to the plugin and set

Excellent idea. I'm still cutting my teeth on this stuff. I'll pursue this

Very excited about the new features Robert, sounds like you're really cracking
on.
I had two thoughts I hope you'll consider integrating:
One is that GLSL is quite poor for initialization. The main problem with this
