Title: Creating a Firework Effect in Unreal Engine | Niagara

Description: Hello everyone, I’m Asif Ali, and you’re watching CGHOW. Today, I will show you how I created this stunning firework effect in Unreal Engine using Niagara. Let’s dive into how I produced this colorful and dynamic firework display!

Key Points:

• Firework Effect Overview: This effect involves rockets shooting randomly into the sky, bursting, and creating colorful trails. The system is mouse-driven, and each click spawns three rockets at random positions.
• Event-Based System: The key to this effect is event handling—using Location Events for the rocket’s trails and Death Events for when the rocket bursts in the sky. These events help control the timing and behavior of the particles.
• Random Color Generation: I used User Parameters in Blueprints to randomize the colors of the firework particles each time they are spawned.
• Creating the Rocket and Burst Effects: I created two emitters—one for the rocket trail and one for the burst when the rocket dies. By generating Location Events in the rocket system, the trail particles follow the rocket’s path. For bursts, I used Death Events to spawn the burst particles when the rocket dies in the sky.

Steps:

1. Rocket Creation: The rocket particles are shot upwards with velocity alignment. I added random movement using curl noise and applied gravity to make them fall slightly.
2. Trail Effect: The rocket trails follow the rocket’s location with the use of location events. I added curl noise and random sizing for a more natural effect.
3. Burst Effect: When the rocket dies, the burst particles are spawned, spreading out in all directions with velocity alignment. I also applied a gravity force to make the burst particles fall.
4. Color Randomization: In the Blueprint, I connected random RGB values to the firework particles, creating a different color each time the fireworks are triggered.

Final Result: A firework effect where every time you click, three rockets shoot into the sky, burst, and leave colorful trails, all with random colors for each launch.

I hope this tutorial helps you understand how to create firework effects in Unreal Engine with Niagara! If you have any questions or need further clarification, feel free to comment below.

Additional Notes:

• Consider tweaking the particle sizes and life spans for more complex effects.
• You can further refine the burst behavior by adding more velocity and noise effects.
