SplineDesign stunning 3D particle effects in real time
Create smoke, sparks, confetti, snow, and abstract particle systems that render in real time. Design emitters visually, drive them with interactions, and ship atmospheric effects that make your web experiences unforgettable.
Particle effects give the best digital experiences their atmosphere and energy.
How particle effects go from first emitter to polished scene
Spline simplifies the entire pipeline for particle design from your first emitter to interactive effects running live in production.
- 01
Ideate
Explore the feel you're after by playing with emitter shapes, spawn rates, and particle life in real time. Remix community particle scenes - rain, fire, confetti, ambient dust - to find a starting point that matches your vision.
- 02
Design
Art-direct every detail: velocity, spread, size and color over lifetime, turbulence, and the materials of the particles themselves. Combine particles with cloner motion, physics, and lighting, and use particle control actions to start bursts on clicks, hovers, or game events.
- 03
Ship to Production
Publish scenes where particles keep simulating live in the browser, or render them to video for film and social content. Optimized real-time rendering keeps effects smooth across desktop and mobile.
Remix Particle Effects from the Community
Discover particle system templates to jumpstart your atmospheric, real-time motion projects.
Questions, answered
Can I create 3D particle effects for free?
Yes! Spline offers a free plan that includes particle systems, so you can design emitters, tune particle behavior, and publish live effects to the web. Perfect for hero section ambience, celebration moments, and atmospheric backgrounds.
How can I start creating particle effects?
Getting started is easy. Add a particle emitter to your scene and watch it run instantly, then shape the effect with visual controls for rate, velocity, size, and color. Remixing a community particle scene is a great way to learn setups fast.
What is Spline and how do its particle systems work?
Spline is a real-time 3D design tool with built-in particle systems. Emitters spawn particles that you style with materials and animate over their lifetime, and everything previews live in the editor exactly as it will run when published.
What kinds of effects can I build with Spline particles?
Snow, rain, smoke, fire, sparks, confetti, floating dust, magical trails, and abstract generative visuals. Particles combine with Spline's cloner motion, hair systems, physics, and post-processing to cover everything from subtle ambience to show-stopping moments.
Can particle effects react to user interactions?
Yes. With particle control actions and Spline's event system, effects can respond to clicks, hovers, scrolling, collisions, and game controls - fire confetti when a user completes a step, or intensify smoke as they approach an object.
Do I need motion design experience to create particle effects?
No. Spline's particle controls are visual and immediately responsive, so beginners can get beautiful results by experimenting. Experienced motion designers get the fine-grained control they expect, without leaving the browser or writing code.
