# Unity URP Simplified Toon Lit Shader Example (for you to learn writing custom lit shader in URP)
|
|||
|
|
|||
|
This repository is NOT the full version shader.
|
|||
|
Currently, this repository is just a very simple and short shader example, only for tutorial purposes, it is under MIT license so you can do whatever you want with the code.
|
|||
|
If you want to keep the current tutorial shader, please fork it or download a copy now since it may be removed in the future.

We are now developing a "easy-to-use + high-performance + cross-platform(include mobile)" Closed source toon shader package - NiloToonURP,
|
|||
|
to meet the toon shading needs of most URP's user.
|
|||
|
|
|||
|
NiloToonURP is tested and working correctly on
|
|||
|
- Unity 2019.4LTS(URP 7.4.1 or above)
|
|||
|
- Unity 2020.3LTS(URP 10.4.0 or above)
|
|||
|
- Unity 2021.1.18f1(URP 11.0.0)
|
|||
|
|

What is included in this "simplified version" toon lit shader repository?
|
|||
|
-------------------
|
|||
|
This repository contains a very simple toon lit shader example, to help people writing their first custom toon lit shader in URP.
|
|||
|
|
|||
|
This example shader's default result(without editing material params) = the following picture
|
|||
|

|
|||
|
|
|||
|
Because this example toon lit shader aims to help people learning shader writing in URP, it is an extremely simplified version of the full version one. This repository only contains ~10% of the full version shader, which only contains the most useful & easy to understand sections, to make sure everyone can understand the shader code easily.
|
|||
|
|
|||
|
It is actually a "How to write your first custom lit shader in URP" example, instead of a good-looking toon lit shader example (lots of toon lit tricks are not included in this example shader, for tutorial reason).
|
|||
|
|
|||
|
Why creating this "simplified version" toon lit shader?
|
|||
|
-------------------
|
|||
|
Lots of my shader friends are looking for a toon lit example shader in URP (not Shader Graph), I want them to switch to URP with me (instead of still staying in built-in RP), so I decided to provide a simple enough URP toon lit shader example.
|
|||
|
|
|||
|
How to try this simplified toon lit example shader in my URP project?
|
|||
|
-------------------
|
|||
|
1. Clone all .shader & .hlsl files into your URP project.
|
|||
|
2. Put these files inside the same folder.
|
|||
|
3. Change your character's material's shader to "SimpleURPToonLitExample(With Outline)"
|
|||
|
4. make sure at least _BaseMap(albedo) is assigned
|
|||
|
5. setup DONE, you can now test your character with light probe/directional light/point light/spot light
|
|||
|
6. edit the material properties to see how the render result changes
|
|||
|
7. Most important: open these shader files, spend some time reading them, you will understand how to write custom lit shader in URP very quickly
|
|||
|
8. Most important: open "SimpleURPToonLitOutlineExample_LightingEquation.hlsl", edit it, experiment with your own toon lighting equation ideas, which is the key part of toon lit shader!
|
|||
|
|
|||
|
I see the shader is working now, but the outline is broken?
|
|||
|
-------------------
|
|||
|
For this tutorial shader, you can let Unity to calculate smooth normal for you, which can produce better outline,
|
|||
|
but doing this will make lighting slightly incorrect.
|
|||
|
|
|||
|
1. click your character's .fbx
|
|||
|
2. In the model tab
|
|||
|
3. edit "Normals" to Calculate
|
|||
|
4. edit "Smoothing Angle" to 180
|
|||
|
|
|||
|

|
|||
|
before calculate smooth normal (printscreen of tutorial shader, not NiloToonURP)
|
|||
|

|
|||
|
after calculate smooth normal (printscreen of tutorial shader, not NiloToonURP)
|
|||
|

|
|||
|
|
|||
|
*NiloToonURP contains a few editor C# scripts, which can help the shader to produce correct lighting and perfect outline together.
|
|||
|
|
|||
|
What is NOT included in this simplified example shader?
|
|||
|
-------------------
|
|||
|
For simplicity reason, I removed most of the features from the NiloToonURP (deleted 90% of the original shader), else this example shader will be way too complex for reading & learning. The removed features are:
|
|||
|
- face anime lighting (auto-fix face ugly lighting due to vertex normal without modifying .fbx, very important)
|
|||
|
- smooth outline normal auto baking (fix ugly outlines without modifying .fbx once you attach a script on character, very important)
|
|||
|
- auto 2D hair shadow on face (very important, it is very difficult to produce good looking shadow result using shadowmap)
|
|||
|
- sharp const width rim light (Blue Protocol / Genshin Impact)
|
|||
|
- tricks to render eye/eyebrow over hair
|
|||
|
- hair "angel ring" reflection
|
|||
|
- PBR specular lighting (GGX)
|
|||
|
- HSV control shadow & outline color
|
|||
|
- 2D mouth renderer
|
|||
|
- almost all the extra texture input options like roughness, specular, normal map, detail map...
|
|||
|
- LOTS of sliders to control lighting, final color & outline
|
|||
|
- per character "dither fadeinout / rim light / tint / lerp..." control script
|
|||
|
- volume override control of global "dither fadeinout / rim light / tint / lerp..."
|
|||
|
- anime postprocessing
|
|||
|
- auto phong tessellation
|
|||
|
- perspective removal per character
|
|||
|
- ***just too much for me to write all removed feature here, the full / lite version shader is a totally different level product
|
|||

How to get a test character model?
|
|||
|
-------------------
|
|||
|
The easiest way to get a character model is by downloading Unity-Chan in the assetstore.
|
|||
|
|
|||
|
Also, here are some websites that can download models(If the creator allows it)
|
|||
|
- https://3d.nicovideo.jp/
|
|||
|
- https://hub.vroid.com/
|
|||
|
|
|||
|
if you downloaded a .pmx file, use MMD4Mecanim to convert it to .fbx & prefab directly inside unity
|
|||
|
http://stereoarts.jp/
|
|||
|
|
|||
|
if you downloaded a .vrm file, use UniVRM to convert it to .fbx & prefab directly inside unity
|
|||
|
https://github.com/vrm-c/UniVRM
|
|||
|
|
|||
|
