Hi Brian, Gees you really need to talk to the guys who set up the shaders about this, I can't comment on stuff I have nothing to do with...

Hi Robert, I realize that enabling or disabling of GL_LIGHTING will have no effect in regard to the shaders. I have implemeneted a way to change a uniform so that lighting can be toggled. My initial attempt at toggling the light uniform was with callbacks. This, as you pointed out, will not work. I know enough OSG to be dangerous, but that is about it. How can I use the OSG standard state inheritance mechanism to help me toggle the light uniform?
