Thanks for your prompt reply on this, I hadn't realized that I have to
declare the uniform. Works a treat now.
Regards,

Hi,
I just tested osg_ViewMatrix on OSG 2.2 win32 binaries using
glsl_dataflag.osg and drawtext4.frag from osgToy, and yes it does
continue
to work.
While osg_ViewMatrix is preset by OSG, you do still have to declare it
in
your shader (eg uniform mat4 osg_ViewMatrix), unlike the gl_* presets.
Turn up the OSG notify level, are you getting any infologs during
compile/link?
