Hi Boon,
This topic has been discussed before. It boils down to the fact, that
Materials/TexGen are fixed function pipeline features. So they are
disabled with GL3.
Long story short: Materials are not support, neither is TexGen.
You will have to write your own shaders and define materials via
uniforms to get the functionality back. I wrote a visitor for this which
would remove the material states from the scene graph and replace them
with uniforms to be sent to a shader (which has to be tailored to your
needs)

Hi,
I managed to compile OSG 3.2 with GL3.h header. In CMAKE, I have checked
only OSG_GL3_AVAILABLE .
However, when I run osgviewer.exe cow.osg, I get the following problem.
Warning: TexGen::apply(State&) - not supported.
Warning: Material::apply(State&) - not supported.
I am using Intel HD4000 graphics on Windows 8, with the latest 9.x
drivers. I have checked that all OpenGL 3.x features are supported.
Can somebody help me explain this problem?
Thank you!
Boon
