## 【Overview : What is UTS/UniversalToon?】

<img width = "800" src="Documentation~/Images_jpg/TPK_04.jpg">

**UTS2 (Unity-Chan Toon Shader 2.0)** is a toon shader for images and video that is designed to meet the needs of creators working on cel-shaded 3DCG animations. Unlike other pre-render toon shaders, **all features can be adjusted in real time on Unity, which is the greatest feature of UTS2**.  

**UTS/UniversalToon** is the UTS2 shader for Universal Render pipeline for Unity.  
**UTS/UniversalToon** has all the feature of UTS2 v.2.0.7.5, and been implemented as an uber shader.

UTS/UniversalToon has great power and makes a wide variety of character designs possible, **from cel-shaded to light novel illustration styles**.  

<img width = "800" src="Documentation~/Images_jpg/UTS2_TopImage02.gif">

UTS/UniversalToon has the 3 basic layers of **Base Color**, **1st Shade Color**, and **2nd Shade Color**, colors and textures can also accept a wide variety of customization options, such as **High Color**, **Rim Light**, **MatCap** (sphere mapping), and **Emissive** (light emission).

What colors will you select as **accent colors**? The accent color is the color which is set at the opposite side of light direction.  

In UTS/UniversalToon, you can use **2nd shade color and Ap-RimLight** as accent color. Of course, these accent colors also change dynamically to the light.

**The level of gradation (feather) between colors can also be adjusted in Unity in real-time**.

In animation production, color design is made for each part in each scene unit. It is common to have specialists who make these color designs. UTS/UniversalToon is suitable for such pipelines.  

In Animation movies, shadows are used not only to represent light directions but also to clarify shapes of characters. It’s not just shadow, but a vital part of character design.  

<img width = "350" src="Documentation~/Images_jpg/UTS2_TopImage06.gif">

For this purpose, UTS/UniversalToon also has 2 options for creating fixed shadows necessary to the design: the **Position Map**, which assigns a set casting point to each shadow, and the **Shading Grade Map**, which can adjust shadow intensity based on the lighting. The movie above is a sample of the features of **Shading Grade Map and AngelRing**.

These two images are comparison between **URP/lit Shader** and **UTS/UniversalToon** under the same lighting conditions.  

Although there is a difference between Photo-realistic and Non-photo-realistic images, you can understand all surface reflections to real-time lights are seen in the same areas. **It means UTS/UniversalToon can be used as same as URP/Lit Shader under various lighting conditions.**  

UTS/UniversalToon is very useful if you want to decorate your game scene with beautiful lightings.

## 【Users' Manual】
**[English manual for v.2.2.0](Documentation~/index.md) is available now.**  

Users' manual is a document with plentiful knowledge of toon style.  
The iteration cycle between reading the manual and using UTS/UniversalToon actually is the best way to learn the beautiful toon style.

## 【Target Environment】
Requires Unity 2019.3.4f1 or higher.  
Requires Universal RP Version 7.3.1 or higher.  
If you use PostProcess Effects, requires Post Procesing Version 2.3.0 or higher.  

This package uses a forward rendering environment. Using a linear color space is recommended.  
(A gamma color space can also be used, but this tends to strengthen shadow gradiation. For more details, see [Linear or Gamma Workflow](https://docs.unity3d.com/ja/current/Documentation~/LinearRendering-LinearOrGammaWorkflow.html). )
