Design 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.
Get started — it's freeParticle effects give the best digital experiences their atmosphere and energy.
Motion and brand designers use Spline's particle systems to add depth, celebration, and ambience to interactive 3D scenes.
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.
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.
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.
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.
