## 📝 Description
![](https://user-images.githubusercontent.com/12690315/41771577-8da4b968-7650-11e8-9524-cd162c422d9d.gif)

This package utilizes the new APIs `MeshBake/MashTrailBake` (introduced with Unity 2018.2) to render particles through
CanvasRenderer.
You can render, mask, and sort your ParticleSystems for UI without the necessity of an additional Camera, RenderTexture,
or Canvas.
