Draws particle prefab thumbnails in project window and adds a richer inspector previews for prefabs, particles, and model assetsA completely free version with the exact same feature set is available on my GitHub. 🆓This editor extension generates custom thumbnails for particle prefabs and adds a custom preview to the Inspector, so you can quickly see the effect without dragging it into the scene.It also enhances previews for 3D and 2D prefabs, as well as model assets, with a grid, improved lighting, camera controls, and useful view modes like Normal, UV, Vertex Color, and more.Features :✨ Thumbnails for particle prefabs🪟 Custom Inspector preview for selected particle prefabs⏱️ Particle playback controls with timeline scrubbing🎯 Motion-aware particle framing for moving effects🧩 Improved preview window for 2D, 3D, and model assets like .fbx and .blend files🖱️ Orbit, pan, zoom, and auto-framing controls📐 Preview grid with optional bounds and collider overlays💡 Better preview lighting with configurable light rig and skybox support🎨 Visual modes including Normal, UV Checker, Vertex Color, Matcap, and Overdraw📊 On-preview stats such as renderer count, triangle count, material count, and bounds size🚀 Cached particle thumbnails for better editor responsivenessNote :⚠️ A Unity Editor restart may be needed after first install or import for smoother preview window hook initialization.⚠️ VFX Graph thumbnails are not currently supported.⚠️ In URP, particle shaders that require the camera opaque texture may render pink in thumbnails and prefab previews. This is not supported by the current preview rendering path.AI was used in multiple steps of developing this package that includes planning, optimizing and preparing the package for production use.
