Hi Goran, In standard OSG (3.2.x, 3.4.0 or the 3.5.x dev series) there isn't any way to automatically remap osg::Material to uniforms so you'll have to run a traverser through the scene graph and replace the osg::Material to osg::Uniform's.
If you are willing to experiment with bleeding edge experimental code then have a look at the shader_pipeline branch of the OSG, in this branch I'm working on a new scheme for automatically mapping old fixed function state like osg::Material to uniforms and #define settings that can then be used by #pragma(tic) shader composition to provide a fully integrated shader+fixed function state solution.
