What is included in this simplified tutorial example toon-lit shader repository?

This repository only contains a very simple toon-lit URP tutorial shader example, to help people write 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 learn shader writing in URP, it is an extremely simplified version. This repository only contains ~3% of the NiloToonURP(full version)'s code, which only contains the most basic & easily understandable sections, to make sure everyone can understand the shader code easily.

It is actually a "How to write your first custom toon-lit shader in URP?" example, instead of a good-looking toon-lit shader (lots of toon-lit tricks are not included in this example shader, for tutorial reasons).

Why create 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(instead of still staying in built-in RP), so I decided to provide a simple enough URP toon-lit shader example in URP.

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, and spend some time reading them, you will understand how to write custom lit shaders in URP very quickly
Most important: open "SimpleURPToonLitOutlineExample_LightingEquation.hlsl", edit it, and 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 calculate smoothed normal for you, which can produce a better outline, but doing this will make the lighting slightly incorrect.

click your character's .fbx
In the model tab
edit "Normals" to Calculate
edit "Smoothing Angle" to 180

before calculating smooth normal (print screen of the tutorial shader, not NiloToonURP)

after calculating smooth normal (print screen of the tutorial shader, not NiloToonURP)

*NiloToonURP(full version) contains a few editor C# scripts, which can help the shader to produce correct lighting and perfect outline together automatically.

What is NOT included in this simplified tutorial shader?

For simplicity reasons, most of the features from the NiloToonURP(full version) are removed, or else for beginners, this simple tutorial example shader will be way too complex for reading & learning. Some of 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 (auto-fix ugly outlines without modifying .fbx and lighting normal, very important)
auto 2D hair shadow on the face (very important, it is very difficult to produce good-looking shadow results on the face using URP's shadow map)
constant width rim light (similar to the method of Blue Protocol / Genshin Impact)
tricks to render eye/eyebrow over hair (ZOffset, stencil, and renderer redraw helpers)
PBR specular lighting (GGX)
all kinds of MatCap features(additive/multiply/shadow/replace...)
"HSV,tint,texture tint,texture override" shadow & outline color control
almost all the extra texture input options like roughness, specular, normal map, detail map, parallax, occlusion, emission...
LOTS of sliders to control lighting style, shadow color, final color, outline, rim light...
per character "dither fade inout / rim light / color control / extra outline / dissolve / ..." control script
volume override control of global "rim light / shadow / color control..."
special bloom post-process volume that can control the param of character/non-character area separately. Usually to prevent character over-bloom, or make the character emitting bloom on allowed areas only
anime postprocessing volume
shadow control volume
perspective removal per character, to avoid character's 3D distorted by high FOV camera
shader stripping editor script, to keep runtime shader memory usage and build time lower
(lots of other features)

just too much for me to write all the removed features here, the NiloToonURP(full version) and this simple tutorial shader example are two totally different products already
