Back To Basics – Fusion: Introduction To Modifiers (Pt 4)

May 15, 2026

Learn DaVinci Resolve Fusion's hidden Modifier system - what they are, finding them, the mental model that makes them click.


Series
Quick Summary

Understand DaVinci Resolve Fusion’s hidden Modifier system – tools that drive parameters from behind the Inspector instead of appearing as nodes in your graph. Walk through Perturb for randomization, Probe for image-driven animation, Expression and Calculation for math between modifiers and parameters, plus the text-driving Scramble, Character Level Styling, and Follower modifiers – then take away the mental model that turns the whole Modifier toolkit from cryptic to genuinely useful.

Learn hidden Fusion tools – and the mental model that makes modifiers click

When you spend time in DaVinci Resolve’s Fusion page, sooner or later you read a tutorial that says “add a Perturb modifier” or “drop in a Probe modifier” – and you cannot find these tools anywhere. Not in the Effects panel. Not in the toolbar. Not in the node graph.

You search every menu, and these modifiers remain invisible.

This is not a missing feature or a hidden plugin. The tools exist – they just live behind the parameters of the tools you already have, not as nodes in your flow.

This fourth installment of the Back to Basics Fusion series unpacks the Modifier system from the ground up. It explains what a modifier is, why Fusion hides them in the Inspector, and how to attach, chain, and remove them. Along the way, it walks through six core modifiers covering both numeric and text-driven workflows.

The deeper payoff is the mental model. Once you understand that a modifier is a tool with inputs and outputs – just like any node, only hidden behind the parameter it drives – the whole system clicks into focus. From there, the Modifier toolkit becomes one of the most efficient ways to build behavior into a Fusion graph without flooding the canvas with extra nodes.


“In theory, a modifier works exactly the same way as a node. So a node has an image output and an image input, mostly. And we direct those outputs to inputs. [Modifiers] have a numerical output and a numerical input. But rather than having all those inputs and outputs clutter our node graph, they are … hidden.”

Bernd Klimm, VFX Artist
After learning how to use Modifiers, you’ll learn that an Expression is the calculator of the Modifier toolkit.

Key Takeaways

By the end of this Insight, you should understand how to:

  • Find modifiers anywhere in Fusion by opening the Modifiers tab on any tool’s Inspector
  • Add a Perturb modifier to randomize a single numeric parameter without keyframes
  • Use the Probe modifier to drive parameters from image luminance instead of timeline keyframes
  • Chain Calculation or Expression modifiers between a modifier’s output and the parameter it drives
  • Animate text characters with Character Level Styling, Scramble, and Follower modifiers
  • Build the mental model that a modifier is a tool with inputs and outputs – just one you never see in the node graph

  • Resolve Fusion – Back To Basics – The parent series this Insight belongs to – Bernd Klimm’s progressive Fusion fundamentals tutorials from first-time-in-Fusion through node graph mastery and beginner troubleshooting.
  • Introduction to Fusion 3D Camera – A series on Fusion’s 3D camera workflow, including animating 3D properties and using expressions to link parameter values across nodes.
  • Animating Text in Fusion – A series on text animation workflows, complementing the text-driving Scramble, Character Level Styling, and Follower modifiers covered in this tutorial.
  • Advanced Keyframe Editing in Fusion – Spline editor and keyframe techniques that pair with modifier-driven animation.
