ToonFragment has strange rendering

Hello,

I already have a functionning surface shader for cel-shading effect. I wanted, for more insight in the field, write an equivalent using only vertex and fragment shader. I more or less managed to do so. I mean, I get no error. But the look is not what I was expecting.




Here's the code: https://github.com/Mehd6384/Shaders/blob/master/UnlitToon.shader

Could anyone explain why this happens ? Instead of having a nice smooth line ?

Also, does anyone know how to see generated code by the surface shader ? I tried cliking but nothing happened.

Thanks !

 

You're doing your cell shading per vertex. That means each vertex is calculating a color and that color gets interpolated between the vertices. For toon shading you really want to do the vast majority of the math in the fragment shader. You're already passing the normal to the fragment shader anyway, so basically copy over everything after calculating the world normal.

For this shader? There's no surface shader here, so there's nothing to generate.

 

You, my friend , are awesome ! Trying this right now.
Nope, I meant for any other surface shader. You have an option "Show generated code" in the inspector

 

Clicking that button will open up the generated shader in whatever you have set for your external script editor (Edit > Preferences > External Tools). If none is set, or if the program selected is not installed, I suspect nothing will happen when you click that button.
