+This package uses the new APIs `MeshBake/MeshTrailBake` (introduced in Unity 2018.2) to render particles through CanvasRenderer.  
+You can render, mask, and sort your ParticleSystems for UI without the need for an additional Camera, RenderTexture, or Canvas.

+### Key Features

-## Demo
+* **Easy to use:** The package is ready to use out of the box.
+* **Sortable:** Sort particle effects and other UI elements by sibling index.
+* **Maskable:** Supports `Mask` or `RectMask2D`.
+* **No extra components required:** No need for an additional `Camera`, `RenderTexture`, or `Canvas`.
+* **Trail module support:** Fully supports the Trail module.
+* **CanvasGroup alpha support:** Integrates with `CanvasGroup` alpha.

 If `ParticleSystem` alone displays particles correctly but `UIParticle` does not, please check the following points:

-* [Shader Limitation](https://github.com/mob-sakai/ParticleEffectForUGUI#shader-limitation)
-  * Most cases can be solved by using `UI/Additive` or `UI/Default`.
-* Particles are masked
-  * `UIParticle` is maskable.
-  * Set `Mask` or `RectMask2D` component properly.
-* Particles are too small
-  * If particles are small enough, they will not appear on the screen.
-  * Increase the `Scale` value.
-  * If you don't want to change the apparent size depending on the resolution, try `Auto Scaling` option.
-* Particles are too many
-  * No more than 65535 vertices can be displayed (for mesh combination limitations).
-  * Please set `Emission` module and `Max Particles` of ParticleSystem properly.
-* Particles are emitted off-screen.
-  * When `Position Mode = Relative`, particles are emitted from scaled position of the ParticleSystem, not from the screen point of the ParticleSystem.
-  * Place the ParticleSystem in the proper position or try `Position Mode = Absolute`.
-* Attaching `UIParticle` to the same object as `ParticleSystem`
-  * `Transform.localScale` will be overridden by `Auto Scaling` option.
-  * It is recommended to place `ParticleSystem` under `UIParticle`.

 UIParticleRenderer renders the particles based on UIVertex.  
-Therefore, only xy components is available for each UV in the shader. (zw components will be discarded).  
-So unfortunately UIParticles will not work well with some shaders.

 When using custom vertex streams, you can fill zw components with "unnecessary" data.

 ### Overheads

-UIParticle has some overheads and the batching depends on uGUI.  
+UIParticle has some overheads, and the batching depends on uGUI.  
 When improving performance, keep the following in mind:
- If you are displaying a large number of the same effect, consider `Mesh Sharing` feature in [UIParticle Component](#uiparticle-component).
-  - If you don't like the uniform output, consider `Random Group` feature.  
-![](https://user-images.githubusercontent.com/12690315/174311048-c882df81-6c34-4eba-b0aa-5645457692f1.gif)
- If you are using multiple materials, you will have more draw calls.
-  - Consider single material, atlasing the sprites, and using `Sprite` mode in the `Texture Sheet Animation` module in ParticleSystem.
