Yesterday there was a discussion on Discord about hypot blending mode. It works better than Screen and Add for comping lights and reflections.
I vibe-coded a matchbox for batch but I think we need it everywhere in Flame. Please upvote the feature request: FI-03614

I’m at the vet with a sick dog right now, but I’ll grab this matchbox and throw up a rig I made based on tony lyon’s Nuke gizmo to match blacks (that works best with hypot)
Hypotenuse function.
Instead of simply adding (A+BA+BA+B) or screening, it adds the energy of the two signals (like a vector length). It works well with floating/over-range values (>1).
Great for lights/reflections/glows: it can feel “punchy” without washing out as aggressively as Add/Screen.
You want to do this in linear color space
