Thanks for this. I’ll do more R&D and let you know what I come up with.

I don't recall if we have an example illustrating setting of uniform struct - I haven't written all the OSG examples or other parts of the OSG code base so can only easily speak off the top of my head of what I've written or have worked closely with, the rest I just look up using grep :-) Although I don't have an example I can point you at, I have used struct in Uniforms before by declaring the struct in the shader source, then in the osg::Uniform setup use a separate osg::Uniform for each uniform i.e. -- GLSL code: struct MyStruct { float a; float b; }; uniform MyStruct mystruct; --- C++ code : stateset->addUniform(new osg::Uniform("mystruct.a", 1.0f)); stateset->addUniform(new osg::Uniform("mystruct.b", 2.5f)); Hope this helps. Robert.
