A commercial test with Clarisse BUiLDER. I have a geometry and a look as input. Then in the graph, I created camera and look variations. You can see laces color variations, main color variations, background variations etc etc... All those variations are driven by variables (you can see them at the top right corner of the full interface snapshot). Finally, I created some processes which loop into each variable and write the rendered image. There are 885 unique rendered images that were rendered with one click once the setup ready. Cheers ;)
