Read this document in other languages: 日本語版

【Overview : What is UTS2?】

Unity-Chan Toon Shader 2.0 (UTS2) 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.

UTS2 has great power and makes a wide variety of character designs possible, from cel-shaded to light novel illustration styles.

UTS2 has the 3 basic layers of Base Color1st Shade Color, and 2nd Shade Color, colors and textures can also accept a wide variety of customization options, such as High ColorRim LightMatCap (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 UTS2, 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. UTS2 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.

For this purpose, UTS2 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 Standard Shader and UTS2 v. 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 UTS2 can be used as same as Standard Shader under various lighting conditions.

UTS2 is very useful if you want to decorate your game scene with beautiful lightings.

Finally, several techniques have been implemented to beautifully display characters in a variety of lighting environments, thanks to recent feedback from VRChat users.

【Users' Manual】

English manual for v.2.0.8 is available now.

Users' manual is a document with plentiful knowledge of toon style.
The iteration cycle between reading the manual and using UTS2 actually is the best way to learn the beautiful toon style.

【Target Environment】

Requires Unity 5.6.x or higher.
The operation check from Unity 2018.2.21f1 to Unity 2019.2.0a9 has been completed.
It has been tested on Unity 2017.4.x LTS, including Unity 2017.4.15f1 LTS.
This pack was created in Unity 5.6.7f1.

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. )
