This is an old scene that I use a lot for testing. Today’s testing was compositing nodes. Using Light groups, drivers, and a couple of odds and sods, I now have a custom compositing node setup (custom for this scene) that allows me to get what was always separate renders in a fraction of the time. One render, many moods. (Ignore the aliasing - this is 71% of full size just to make posting easier).
Sure - I selected 5 light groups, one with the sun, one for the environment, one for the ceiling lights, one for the desklamp and one for the cigarette smoke (that needed to be emission otherwise it would become invisible), then I started to plug the nodes together.
Almost impossible to explain how I put it all together here. If I get a chance at weekend, I’ll throw a video tutorial together. There will be no modelling or texturing - just putting together the compositing nodes.
