Any time I change Render Size it ruins all of my node-tree setup. Common workflow in compositor is to work in some lower resolution to set wanted effect. Like 50% or 25% of final size. But many values are based on current image size on input.

Does there exist any math combination that can be applied to a node-tree to protect the result? A math equation that can equally increase or decrease values in one place?

This gif example is using the same node-tree to generate a lens flare. Rendered on 10%, 25%, 50%, 100%

The current compositor is not relatively aware. Hence some pixel based nodes give different on different resolutions. There is a new design for the compositor that will overcome this issue, but this still needs a lot of development time. https://developer.blender.org/T53790

  • Thanks, it's a shame, any chance for same workaround? – vklidu Jan 19 '18 at 10:34
  • Inside blender there is no work around to my knowledge. Normally I composite in the highest resolution (100%) and downscale afterwards using image magic. – J. Bakker Jan 19 '18 at 10:43
  • I would love to so :) but my comp is not fast enough for complex node-trees :) Current situation also make totally impossible sharing node groups with others. I hope your link is a near future. Thanks – vklidu Jan 20 '18 at 11:12
