Hey there,

Let’s talk about one of the most powerful tools in a VFX artist’s toolbox: Particle Systems!

At its core, a particle system is a system that spawns, controls & animates particles that work together to create a larger VFX.

Let's break down the key components of a particle system:

EMITTERS

Think of emitters as the “spawn point” of your particles. These are the containers where particles are created. You can shape emitters (sphere, box, mesh) to control where & how particles appear.

PARTICLES

These are the building blocks of your emitter. Each particle is a singular visual element For eg:

A raindrop.
A spark.
A puff of smoke. 
An ember.
A snowflake.
A campfire would consist of fire, refraction, smoke & ember particles.

PROPERTIES

Each particle has properties that you can customize. They define how your particle's color, size, speed or lifetime behave

DYNAMIC PARAMETERS

Allows you to control parameters inside your shader. You can use this to add complex details to your particle properties.

MODULES

Basic scripts that allow you to control particle properties. There are pre-built modules or you can create your own using visual scripting in Niagara.

FORCES

Use forces to make your particles move dynamically. Want your particles to fall, swirl or explode outward? Use forces like gravity, velocity, drag, or turbulence.

CURVES

Here’s where the magic happens. Curves let you animate how a particle behaves over its lifetime.

Imagine a spark that starts bright & large - then shrinks & fades out.

That’s all done with curves - controlling it's color & size over it's life.

RENDERERS

Particles need a visual identity. Renderers define the look & feel.

Sprite - Renders particles as 2D textures (sprites) facing the camera. Useful for effects like smoke, fire or sparks.
Mesh - Renders particles as 3D static meshes. Ideal for debris, rocks or shader based FX.
Ribbon - Connects sequential particles into continuous trails or ribbons. Used for laser beams or magic trails.
Light - Spawns lights at particle locations by inheriting color. Use in limited quantities if building for lower end systems.
Decal - Projects materials onto scene geometry. Can be used for magic circles or blood splatter.

FINAL THOUGHTS 🎯

Particle systems are not about memorizing buttons. Start Small, Learn Fast.

You don’t need to build the next AAA explosion today. Start with one emitter and spawn a few particles. Experiment with one property at a time and watch your VFX come to life!
