-* [4.0.0+] Mesh sharing group to improve performance.  
-  ![MeshSharing.gif][MeshSharing.gif]
-* [4.0.0+] Particle attractor component.  
-  ![ParticleAttractor.gif][ParticleAttractor.gif]
-* [4.1.0+] Relative/Absolute particle position mode.

-## ⚙ Installation
-
-_This package requires Unity 2018.3 or later._
-
-#### Install via OpenUPM
-
-This package is available on [OpenUPM](https://openupm.com) package registry.
-This is the preferred method of installation, as you can easily receive updates as they're released.
-
-If you have [openupm-cli](https://github.com/openupm/openupm-cli) installed, then run the following command in your
-project's directory:
-
-```sh
-openupm add com.coffee.ui-particle
-```
-
-#### Install via UPM (using Git URL)
-
-Navigate to your project's Packages folder and open the `manifest.json` file. Then add this package somewhere in
-the `dependencies` block:
-
-```json
-{
-  "dependencies": {
-    "com.coffee.ui-particle": "https://github.com/mob-sakai/ParticleEffectForUGUI.git",
-    ...
-  }
-}
-```
-
-To update the package, change suffix `#{version}` to the target version.
-
-* e.g. `"com.coffee.ui-particle": "https://github.com/mob-sakai/ParticleEffectForUGUI.git#4.6.0",`
-
-Or, use [UpmGitExtension](https://github.com/mob-sakai/UpmGitExtension) to install and update the package.
-
-<br><br>
-
-## 🚀 Usage
-
-### UIParticle Component
-
-`UIParticle` controls the ParticleSystems that are attached to its own game objects and child game objects.
-
-![](https://github.com/mob-sakai/ParticleEffectForUGUI/assets/12690315/3559df45-63e7-4c4c-9233-f455779efa29)
-
- **Maskable**: Does this graphic allow masking.
- **Scale**: Scale the rendering. When the `3D` toggle is enabled, 3D scale (x, y, z) is supported.
- **Animatable Properties**: If you want to update material properties (e.g., `_MainTex_ST`, `_Color`) in AnimationClip,
-  use this to mark the changes.
- **Mesh Sharing**: Particle simulation results are shared within the same group. A large number of the same effects can
-  be displayed with a small load. When the `Random` toggle is enabled, it will be grouped randomly.
- **Position Mode**: Emission position mode.
-    - **Absolute:** Emit from the world position of the `ParticleSystem`.
-    - **Relative:** Emit from the scaled position of the `ParticleSystem`.
- **Auto Scaling**: `Transform.lossyScale` (=world scale) will be set to `(1, 1, 1)` on update. It prevents the
-  root-Canvas scale from affecting the hierarchy-scaled `ParticleSystem`.
- **Rendering Order**: The ParticleSystem list to be rendered. You can change the order and the materials.
-
-**NOTE:** Press the `Refresh` button to reconstruct the rendering order based on children ParticleSystem's sorting order
-and z-position.
-
-<br><br>
-
-#### Basic Usage
-
-1. Select `GameObject/UI/ParticleSystem` to create UIParticle with a ParticleSystem.
-   ![particle](https://user-images.githubusercontent.com/12690315/95007361-cad0e880-0649-11eb-8835-f145d62c5977.png)
-2. Adjust the ParticleSystem as you like.
-   ![particle1](https://user-images.githubusercontent.com/12690315/95007359-ca385200-0649-11eb-8383-627c9750bda8.png)
-
-<br>
-
-#### With Your Existing ParticleSystem Prefab
-
-1. Select `GameObject/UI/ParticleSystem (Empty)` to create UIParticle.
-   ![empty](https://user-images.githubusercontent.com/12690315/95007362-cb697f00-0649-11eb-8a09-29b0a13791e4.png)
-2. Drag and drop your ParticleSystem prefab onto UIParticle.
-   ![particle3](https://user-images.githubusercontent.com/12690315/95007356-c6a4cb00-0649-11eb-9316-562f4bce3f31.png)
-
-<br>
-
-#### With `Mask` or `RectMask2D` Component
-
-If you want to mask particles, set a stencil-supported shader (such as `UI/UIAdditive`) to the material for
-ParticleSystem.
-If you use some custom shaders, see
-the [How to Make a Custom Shader to Support Mask/RectMask2D Component](#how-to-make-a-custom-shader-to-support-maskrectmask2d-component)
-section.

-
-<br><br>
-
-### Script usage
-
-```cs
-// Instant ParticleSystem prefab with UIParticle on runtime.
-var go = GameObject.Instantiate(prefab);
-var uiParticle = go.AddComponent<UIParticle>();
-
-// Control by ParticleSystem.
-particleSystem.Play();
-particleSystem.Emit(10);
-
-// Control by UIParticle.
-uiParticle.Play();
-uiParticle.Stop();
-```

-
- **Particle System**: Attracts particles generated by the specified particle system.
- **Destination Radius**: Once the particle is within the radius, the particle lifetime will become 0, and `OnAttracted`
-  will be called.
- **Delay Rate**: Delay to start attracting. It is a percentage of the particle's start lifetime.
- **Max Speed**: Maximum speed of attracting. If this value is too small, attracting may not be completed by the end of
-  the lifetime, and `OnAttracted` may not be called.
- **Movement**: Attracting movement type. (`Linear`, `Smooth`, `Sphere`)
- **Update Mode**: Update mode.
-    - **Normal:** Update with scaled delta time.
-    - **Unscaled Time:** Update with unscaled delta time.
- **OnAttracted**: An event called when attracting is complete (per particle).

-### 🔍 FAQ: Why Are My UIParticles Not Displayed Correctly?
-
-If `ParticleSystem` alone displays particles correctly but `UIParticle` does not, please check the following points:
-
- [Shader Limitation](#shader-limitation)
-    - `UIParticle` does not support all built-in shaders except for `UI/Default`.
-    - Most cases can be solved by using `UI/Additive` or `UI/Default`.
- Particles are not masked
-    - `UIParticle` is maskable.
-    - Set `Mask` or `RectMask2D` component properly.
-    - [Use maskable/clipable shader](#how-to-make-a-custom-shader-to-support-maskrectmask2d-component) (such
-      as `UI/Additive` or `UI/Default`)
- 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 the `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 the 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 the `Auto Scaling` option.
-    - It is recommended to place `ParticleSystem` under `UIParticle`.
- If `Transform.localScale` contains 0, rendering will be skipped.
- Displayed particles are in the correct position but too large/too small
-    - Adjust `ParticleSystem.renderer.Min/MaxParticleSize`.
-

-
-### Shader Limitation
-
-The use of UI shaders is recommended.
-
- If you need a simple Additive shader, use the `UI/Additive` shader instead.
- If you need a simple alpha-blend shader, use the `UI/Default` shader instead.
- If your custom shader does not work properly with UIParticle, consider creating a custom UI shader.
-
-#### Built-in shaders are not supported
-
-`UIParticle` does not support all built-in shaders except for `UI/Default`.  
-If their use is detected, an error is displayed in the inspector.  
-Use UI shaders instead.
-
-#### (Unity 2018 or 2019) UV.zw components will be discarded
-
-UIParticleRenderer renders the particles based on UIVertex.  
-Therefore, only the xy components are available for each UV in the shader. (zw components will be discarded).  
-So unfortunately, UIParticles will not work well with some shaders.
-
-#### (Unity 2018 or 2019) Custom vertex streams
-
-When using custom vertex streams, you can fill zw components with "unnecessary" data.  
-Refer to [this issue](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/191) for more information.
-
-<br>
-
-### Overheads
-
-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 the `Mesh Sharing` feature in
-  the [UIParticle Component](#uiparticle-component).
-    - If you don't like the uniform output, consider the `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 a single material, atlasing the sprites, and using `Sprite` mode in the `Texture Sheet Animation` module
-      in the ParticleSystem.
