How to Use Niagara in Sequencer: Unreal Engine 5.4 Guide

Описание: Want to take your visual effects from real-time to cinematic? In this essential UE5.4 guide, your host, Ashif Ali, a RealtimeVFX artist from India, will teach you to seamlessly integrate and animate Niagara particle systems directly within Unreal Engine's Sequencer. You'll learn the key to creating stunning, pre-scripted VFX sequences for cinematics, cutscenes, and trailers.

This video is a must-watch for game developers and VFX artists who want to master the powerful combination of Niagara and Sequencer. I will walk you through the entire process, from adding your effect to controlling every parameter over time.

What You'll Learn:
✅ Adding Niagara to Sequencer: Understand the proper workflow for placing and managing your Niagara systems in a cinematic timeline.

✅ Keyframe Parameters: Master the art of keyframing to control the size, color, velocity, and other properties of your VFX over a specific duration.

✅ Timeline Control: Learn how to use Sequencer's timeline to precisely time your effects with other events, such as camera movements or sound cues.

✅ Cinematic Application: Discover how this technique is used in professional game development to create visually compelling story moments.

0:00 Intro & The Old Forum Question: Frame-Locking Niagara for Scrubbing
0:36 Part 1: Basic Sequencer Setup & Niagara Integration
0:36 Creating a Cinematic Level Sequencer asset
1:07 Adding Niagara: Dragging the Niagara System into the viewport or directly into the Sequencer
1:43 Accessing Parameters (Niagara Component): Selecting the Niagara System and adding the Niagara Component track for full parameter control
2:34 Controlling Life Cycle with Spawn Keys
2:46 Setting the Niagara System to Spawnable
2:52 Using the Spawn Track (Red/Green Keys) to activate/deactivate the effect on specific frames (causes instant particle death)
3:35 Controlling Life Cycle with the Life Cycle Track
3:35 Using the Life Cycle Track (Yellow Bar) to define the duration (particles fade out naturally)
4:29 Part 2: The Answer! Frame-Locking for Scrubbing
4:32 Selecting the Niagara Component
4:43 Adding the Life Track (Desired Age) option
4:47 Result: The particles now follow the timeline precisely, allowing you to scrub backward and forward while particles snap to the correct state
5:05 Note: Checking the Desired Age property (for older UE versions)
5:26 Part 3: Attaching Niagara to Animation/Bones
5:32 Adding a Skeletal Mesh (Character Walk) to the Sequencer
6:30 Attachment Setup: Going to the start frame and using the Attach track
7:01 Selecting the Target Bone (e.g., LeftToesBase) for attachment
7:09 Attachment Range: Ensuring the Attachment Track bar covers the entire section of the animation
7:38 Local Space Offset: Adjusting the particle system's position relative to the bone while attached
8:17 Part 4: Keying Effects to Steps (Dust Example)
8:26 Creating a basic Dust Burst effect (Burst Instantaneous)
9:31 Syncing: Animating the Dust effect's Spawn Track (Spawn/Deactivate) to precisely match the character's footfalls
11:22 Part 5: Animating User Parameters
11:39 Spawn Rate: Creating a Spawn Rate User Parameter in Niagara
12:09 Keying Spawn Rate: Adding the Spawn Rate User Parameter to the Sequencer and keying it from 0 to 200 (Burst Start) and back to 0 (Burst End) to control particle count
13:26 Color/Shade: Creating a Shade (Float) User Parameter to control brightness
13:53 Keying Shade: Keying the Shade Parameter to spike the brightness (e.g., to 500) for a few frames for a strong flash
14:49 Part 6: Caching Niagara Fluids (Optimization)
14:55 The Problem: Heavy fluid effects (like an Explosion) often stutter during playback
16:10 The Solution (Niagara Cache): Adding the Niagara Cache Track
16:19 Hitting the Record Button to pre-simulate and Cache the heavy fluid simulation
16:40 Result: Smooth, high-resolution playback and scrubbing of the fluid simulation
17:44 Conclusion
