What it is

ParticleEffectForUGUI renders Unity particle systems directly within uGUI canvases using MeshBake and MeshTrailBake APIs (introduced in Unity 2018.2) to generate baked meshes that are fed to CanvasRenderer. The core innovation is masking and z-sorting particles natively in UI without requiring extra Camera, RenderTexture, or Canvas layers—eliminating significant rendering overhead. Standard UPM package structure: Runtime/ contains core UIParticle.cs component and extension utilities (CanvasExtensions, Vector3Extensions, Color32Extensions); Editor/ has UIParticleEditor.cs inspector and UIParticleMenu.cs context menus; Internal/ utilities and project settings; samples in…

Start here

Open these first:

• Runtime/UIParticle.cs — Core component that manages particle effect rendering in uGUI—entry point for all particle system integration and the…
• Runtime/UIParticleRenderer.cs — Handles the actual rendering pipeline, mesh generation, and material application for particles within the uGUI canvas.
• Runtime/UIParticleUpdater.cs — Manages per-frame updates of particle systems and synchronization with the UI rendering loop.
• Runtime/Internal/Utilities/MaterialRepository.cs — Caches and manages material instances to avoid redundant material creation and memory overhead.
• Runtime/AnimatableProperty.cs — Enables dynamic animation of particle properties through Unity's animator, a key differentiator of this package.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repo: git clone https://github.com/mob-sakai/ParticleEffectForUGUI.git. Install via OpenUPM: openupm add com.coffee.ui-particle. Or add to package.json manually: add "com.coffee.ui-particle": "4.12.1" to…

Daily commands:

No server or build required. Unity Editor handles execution: open the project in Unity 2018.2+, load Samples~/Demo scene, and press Play. The package is purely a component library—integrate by adding UIParticle compon…

Key cautions & unknowns

• Concentrated ownership — top contributor handles 66% of recent commits
• Could not verify tests, CI from the available repository evidence
• MeshBake/MeshTrailBake APIs are Unity 2018.2+—no fallback for older versions. Particle shader compatibility depends on target graphics API (requires desktop/console shaders, mobile may need URP variants). Canvas…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
