Unity Particle System Previewer

Particle System Previewer is a Unity Editor extension designed for VFX artists, technical artists, and game developers who need a faster way to browse, preview, analyze, and capture Particle System prefabs.

Instead of repeatedly placing effects into test scenes, you can inspect Particle System prefabs from a dedicated preview window inside the Unity Editor.

KEY FEATURES

• Particle System Prefab Browser

Scan a selected Assets folder and optionally include subfolders.

Browse prefabs using thumbnails, search, favorites, recent items, and issue filters.

• Playback Controls

Play, pause, stop, restart, loop, adjust playback speed, and inspect effects using timeline controls.

• Preview Camera

Orbit, zoom, adjust camera FOV, change the background color, use a custom skybox, and display a configurable ground grid.

• Projectile Preview

Preview the selected effect as moving projectiles using straight, circular orbit, and parabolic movement modes.

• Particle Analysis

Analyze Particle System prefabs using Mobile, PC, and VR-oriented performance guidelines.

• Max Particles Optimizer

Calculate recommended Max Particles values and apply optimizations with configurable safety margins and Unity Undo support.

• Material Validation

Check Particle System renderer materials and identify missing, Built-in, custom, or potentially incompatible URP materials.

• Overdraw Preview

Replace preview materials with a heat-style additive visualization to identify areas with excessive transparent particle overlap.

• PNG Capture

Export a single PNG image or a PNG sequence with adjustable resolution, FPS, duration, transparent background, and grid visibility.

• Multilingual Interface

English, Korean, and Japanese interface support.
