This project is a demo of my Cel Shader for Godot 4. This is a continuation of this project, the old version of this shader for Godot 3. Feel free to mess around with it and study!
You need to put everything on the src folder on your project, on the same folder. Then, go to Project Settings > Shader Globals and set the following:
float specular_smoothness = 0.05
float fresnel_smoothness = 0.05
float outline_width = 4
color outline_color = black
These values are the ones that made this screenshot you're seeing, but feel free to mess around with these values.
Whenever you want a material with one of the additional features, make a copy of cel-shader-base.gdshader and change the defines.
This is how the defines look on cel-shader-base.gdshader. For each feature you want, change the 0 to 1 and the additional uniforms should show up on the material. You must have the includes folder on the same directory as the your modified copy. You can see the demo as an example.
Lastly, you can watch the Youtube video for more information on how the base functions work and how to set it up.
Make another material with the outline.gdshader shader. Put this material on the next_pass property of the material.
