What you want sounds similar to texture splatting. It is not necessarily
per vertex but it is a way of having multiple areas of different
textures/materials within a single geometry. I use it in osg when
rendering terrain. Maybe you can do something similar with your
materials as described in:

Unfortunately I need to set the ambient, diffuse, specular, and

level I have been able to find that allows me to apply materials in OSG
is at the Geometry class, through a StateSet. Is this the case or am I
overlooking something?

Which material properties do you need to modify? If you only need to
change the ambient and diffuse colors, for example, you could use the
color material feature.

Subject: [osg-users] Setting Materials at a vertex level
I am trying to build a scene graph in which I need to set material
properties for each vertex in a drawable. Does OSG support the ability
to set materials per vertex?
