Tired of manually adjusting every parameter to change the size of your effects? In this essential UE5 Niagara tutorial, you'll learn how to master FX scaling and control everything from size and velocity to color with a single parameter! Your guide, Ashif Ali, a RealtimeVFX artist from India, will teach you a powerful workflow that makes your effects more dynamic and reusable than ever before.
This video is a must-watch for game developers and VFX artists who want to optimize their workflow and create highly customizable, scalable effects. We'll show you how to set up user parameters to control your entire system with ease.
What You'll Learn:
✅ Parameter Control: Master the essential steps to create a single user parameter that controls multiple aspects of your effect.
✅ Optimized Workflow: Learn how to quickly and efficiently scale your entire particle system to fit different sizes and situations.
✅ Dynamic Effects: Discover how this technique allows for a single effect to be used for multiple purposes, from a small puff of smoke to a massive explosion.
✅ Real-world Application: I'll show you how to apply this workflow to various effects to speed up your development process.

0:00 Intro & Final Scaled VFX Preview
0:17 The Problem: Scaling a Niagara system from the viewport breaks internal particle proportions.
0:33 Part 1: The Principle (Scaling Simple Emitter)
1:23 Creating a User Parameter (Float) named Scale FX
2:00 Connecting Scale FX to the Sprite Size
2:43 Connecting Scale FX to the Sphere Location Size
3:19 Key: Connecting Scale FX to Forces (Multiplying Initial Velocity by Scale FX)
3:47 Key: Connecting Scale FX to Gravity (Multiplying Gravity Force by Scale FX)
4:10 Result: Demonstrating that all parameters (size, velocity, gravity) now scale proportionally.
4:31 Part 2: Scaling a Complex Multi-Emitter FX
4:58 Emitter 1 (Stars): Connecting Scale FX to the Sprite Size
5:30 Emitter 2 (Main Particles): Connecting Scale FX to the Sphere Shape Location Size
5:52 Connecting Scale FX to Initial Velocity
6:00 Connecting Scale FX to Curl Noise Force (Multiply the force amount)
6:20 Emitter 3 (Ring): Connecting Scale FX to Ring Sprite Size
6:32 Emitter 4 (Refraction): Connecting Scale FX to the Sprite Size (Multiplying its base value of 1.5)
6:48 Final Result: Duplicating the complex effect and changing only the Scale FX parameter to see proportional scaling.
7:27 Conclusion: Why you should use this User Parameter technique for scaling.
