Поместить 2 сценария шейдеров в 1 сценарий шейдера (Bend World мультяшный шейдер)

Вопрос:

У меня есть 2 шейдера, которые работают индивидуально. изогнутый мир и мультфильм, который я подобрал здесь https://github.com/unity3d-jp/UnityChanToonShaderVer2_Project .

вот 2 соответствующих сценария.

Изогнутый

 Shader "Custom/Curved"

Извините, это немного запутанно, но я действительно не знаю, как это сделать, я копирую / вставляю одно в другое, и это не работает … я действительно не понимаю, как работают шейдеры.

Комментарии:

1. Мультяшный шейдер включает cginc в себя другие файлы, которые определяют vert . UCTS_Outline.cginc , UCTS_DoubleShadeWithFeather.cginc , и т.д. Хорошим началом было бы определить Curve функцию из изогнутого кода и вызвать ее в начале vert функций в этих .cginc файлах и перезаписать значение v.vertex, с которым они работают, например VertexOutput vert (VertexInput v) { v.vertex = Curve(v.vertex); /* rest of vert function */}

2. И где мне найти VertexOutput vert в мультяшном шейдере?

3. Мультяшный шейдер включает в себя другие файлы cginc, которые определяют vert. UCTS_Outline.cginc , UCTS_DoubleShadeWithFeather.cginc , и т.д.

4. хорошо, итак, я помещаю изогнутую функцию во все остальные файлы cginc и перезаписываю вывод с VertexOutput vert (VertexInput v) { v.vertex = Curve(v.vertex); /* rest of vert function */} помощью? это так? извините, я немного новичок в шейдерах

5. Готово, это работает! Я, наконец, понял, я ввел глобальную переменную, объявил кривую функции и поместил новую v.vertex в VertexOutput vert для каждого UCTS. Спасибо за вашу помощь и за то, что нашли время 🙏 @Ruzihm
