This has been discussed multiple times, have you tried searching the
archives for "transparent" or "blend"? There are also several examples that
show how to do this. Try doing a recursive, case-insensitive grep on your
OSG source tree for "transparent".
The rules for transparency in OSG are not different from those of OpenGL. Do
it just like you would in OpenGL, except use the StateSet setRenderingHint
to control render order.

No one have any idea of how to set an alpha transparency level on a geometry
It has no texture, juste one color...

Just a simple question on how to set a transparency effect on a drawable.
My geode contains 2 drawables, and I need only one to be transparent...
I've tried :
double opacity = 0.1;
osg::StateSet* state = mygometry->getOrCreateStateSet();
osg::Material* mat =
mat = new osg::Material;
Lightning is already set to ON...
But nothing appear transparent...
