Please note roughness has no effect on volume rendering at all. I'm afraid what you are seeing has nothing to do with lighting but with the way interpolation and volume...

Can you explain what you have in mind in more details ? I fail to see how `vtkTimerLog` would help, its merely a start/stop counting timer. You can put it...

Its different but is it wrong ? Should we "fix" the rendering of Blur/SSAO/Grid to look similar at any resolution ? Or do you mean that we should fix it...
