[SUBMISSION] PROPAGATE - change parameters across multiple nodes [SUBMITTED]

[eklektyczny]

PROPAGATE is a utility that captures parameter changes on the active node and applies them to other selected nodes, keeping settings, connections, expressions, and animations consistent across a selection. It streamlines multi-node work by supporting all parameter types with special handling for Loader/Saver tools, point inputs, and keyframed animation.

I've recorded short showcase:

This looks great! I wasn’t able to try it yet but I’m looking forward to it.

Back when Andrew wrote about the action manager I was eager to implement an action script that checks for changes of parameters and applies them to all selected nodes. Unfortunately, there wasn’t a trigger for parameter changed and I gave up in favor of the /for commands.

This implementation looks very promising. Especially if it’s added to a shortcut.

Excellenczny! Front page!

Thank you for sharing!

[SecondMan]

OMG the connections thing!

[SecondMan]

Can I be really greedy please?

A Relative mode - so instead of propagating the same value, imagine you have a setup with multiple (say 4) nodes that have the same parameter set to 0, 0.2, 0.5, and 0.75.

I want to add 0.1 to each parameter. Or I want to multiply all by 1.25...

Excellent idea!

Thank you for the fronty page. It's a honor

This is an excellent idea. I am not 100% if that shouldn't be a seperate tool to prevent feature creep.
BTW I completely missed the connections part, since I thought I had the tool figured out before the end of the video.
The connections thing is wild indeed!

Lovely stuff as usual<3

Got some UI feedback for you:

• A shortcut for closing the Propagate window be nice - using same as opening the window (i) seems nice to me. Maybe add ctrl/cmd + w (as with the Expression Editor) to that?

• Technically the "Active" node is a selected node. So the correct number of "selected" nodes should include the active one too. Technically correct being, as we all hopefully know, the best kind of correct.

• The "Cancel" button doesn’t really seem to cancel anything. Since the window already has a native close button (at least on my Mac, I can’t really tell from the video/screenshot if that title bar button is active or even meant to be a close button), it feels redundant.

  On top of that, calling it "Cancel" signals that it does something different (I.E. cancel a process and/or reverting to the initial state of things before any propagate action may have occurred), but it doesn’t.

  My suggestion would be to either remove it (my pick, especially if a shortcut for closing the window gets added as in point #1), or rename it to “Close.” But then you end up with two close buttons in a tiny window, which feels like one too many (again, depending on what that title bar button is actually doing in the demo).

Good suggestions! I will implement this in the next round.

it's the best plugin for fusion ( after reactor ofc hhh ) because it's saves a lot of time ,no way to run it in the free version ?

[SecondMan]

no way to run it in the free version

EDIT

1. buy Fusion Studio,
2. support independent creators,
3. support We Suck Less.

[AndrewHazelden]

no way to run it in the free version ?

The toolset would work in Resolve Free v19.0.3 as the final compatible version that supported GUI based scripting. After that specific release, BMD depreciated their own GUI creation framework in Resolve Free. If you want to run a Resolve release like 19.1 - 20.1+ with the propagate toolset you would need to be on Resolve Studio.

Hey @eklektyczny! Thanks for this amazing tool! I have a suggestion: what about adding the ability to select multiple nodes and then apply an specific tool multiple times for each one? For example, if I have 15 Text+ nodes and I want to add a Blur node to each one, it would be great to do it in one go.

This can be useful! I will think about how this can be done.

v1.1 2026-1-8

• Fixed false positive "disconnected" detection for animated parameters

• Fixed false positive value change detection for connected inputs

• Filtered out internal "Clone" parameters (e.g., BlendClone) from change detection

• Fixed duplicate connection change log messages

• Fixed redundant "became animated" detection when connection change is already detected

• Fixed keyframe deletion propagation - now properly disconnects BezierSpline animation

• Fixed issue where connections were incorrectly detected as animations

• Add more hotkeys for closing the window (Escape, I, Ctrl+W). "I" works without the window ins focus

• Remove "Cancel" button
