Compositor - How to math same Result for any Render Size Any time I change Render Size it ruins all 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 exist any math combination that can be applied to a node-tree to protect result? A math that equally increase or decrease values in one place?

In this gif example is used the same node-tree to generates 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
