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?

Clone all .shader & .hlsl files into your URP project.
Put these files inside the same folder.
Change your character's material's shader to "SimpleURPToonLitExample(With Outline)"
make sure at least _BaseMap(albedo) is assigned
setup DONE, you can now test your character with light probe/directional light/point light/spot light
edit the material properties to see how the render result changes
Most important: open these shader files, spend some time reading them, you will understand how to write custom lit shader in URP very quickly
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.

click your character's .fbx
In the model tab
edit "Normals" to Calculate
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
