유니티 2021 URP Toon Shader

 

이미 URP 툰 쉐이더는 유명한 소스가 있다

 

https://github.com/ColinLeung-NiloCat/UnityURPToonLitShaderExample

GitHub - ColinLeung-NiloCat/UnityURPToonLitShaderExample: A very simple toon lit shader example, for you to learn writing custom

 

 

다만 이건 2023 부터 지원이라 2021 에서는 쓸 수가 없어서 좀 개조

 

잘 나온다

 

 

위의 UnityToonShader 를 유니티에 적용하고 쉐이더 파일을 하나 카피

해서 아래 코드로 바꿔주면 되겠다
