I have exactly the same needs, and I use the same solutions ! - Some of my "per-view" uniforms are "static" : their value never change => those are added on viewer's camera's stateset - Some of my "per-view" uniforms are "dynamic" : their value change at each frame (based on camera position, user settings, a specific object position...) => those are pushed at cull traversal : the view is identified from the cullvisitor, specific value computation is done there and the uniform is pushed.
