[Overview]
KoiKatu Unity-chan Toon Shader
As the name suggests, it is a modified Unity-Chan Toon Shader for Koikatsu.
With conventional general-purpose shaders, various sliders, nipples, pubic hair and other textures are not displayed, etc.
It was difficult to use as a body texture.
This is not all, but it corresponds to various sliders to some extent, and it is also possible to display the texture of the nipple and pubic hair.
See below for Unity-Chan Toon Shader.

[How to use]
1. Put the zip mod file in the mods folder.
2. Set the body and face shaders to KKUTS in the Material Editor.

[Explanation of parameters]
Please refer to the following.
https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project/blob/release/legacy/2.0/Manual/UTS2_Props_en.md

[About CullMode]
Normally, transparent shaders do not render the back side.
Therefore, if you apply a transparent shader to an object with a visible back side, such as a skirt, it will appear transparent from the back side.
To avoid this, we have added the parameter CullMode, which allows you to select whether to render the backside.
When set to "0", the backside of the image will be rendered, but some objects will not be rendered correctly.
When set to "2", only the front side of the object is depicted as usual.
If you set it to "1", only the back side of the object is depicted, which is not useful at this time.

[About the foreground display of eyes and eyebrows]
KKUTSHair can now transparently display hair when the eyes and eyebrows are displayed in the foreground.
You can change the transparency by adjusting the parameter Tweak_Transparency of KKUTSHair.

[About KKUTSeye (for eyes) and KKUTSeyew (for whites of eyes)]
When using lights other than the character lights, only the eyes light up or darken because the default shaders for the eyes are not supported.
Therefore, we have created a KKUTS-specified shader for the eyes.
The eyew can also be used for eyebrows and eyeliner.

[About Tessellation].
A shader function that subdivides and smoothes the mesh. （It is equivalent to high-poly.)
Please be aware that DX11 is required and the GPU load is reasonably high.

[Known bug]
Some vanilla sliders do not work.

If alpha objects overlap, some may disappear.
If you want to fix it, adjust the render queue.

When displaying transparency to the eyes and eyebrows, for some reason the eyeliner may appear to be more fully visible than the hair.

The liquid representation may differ slightly from vanilla.

The color behavior of the outlines is different from vanilla because the behavior of vanilla outlines is not fully simulated.
If you want to correct the color tone, use "OutlineColor_Adjust" to adjust it.
In some cases, if the original color is too dark, the outline will be completely black. In this case, try lowering the value of "Is_BlendBaseColor" a little.

There was a bug in MAKER that left an afterimage when tessellation was enabled.
To address this issue, we have included a plugin that enables the depthnormal mode of the camera.
Please note that the above bug will occur if you do not install this plugin.

[About Vanilla Sliders]
Some parameters, such as color, lip gloss, and fleshiness, can be set both in the Vanilla slider and in the Material Editor.
Please note that the Material Editor settings will take precedence over the vanilla sliders.

[About KKManager]
KKUTS is now also introduced in KKManager.
This may cause conflicts, so if you are experiencing problems, please try deleting the following
