I want to try the shader of the this sites.
Shader "Hidden/Vignetting" {
Properties {
_MainTex ("Base", 2D) = "white" {}
_VignetteTex ("Vignette", 2D) = "white" {}
_GlitchTex ("Glitch", 2D) = "white" {}

However, shader becomes the error.
Shader error in ‘Hidden/Vignetting’: syntax error: unexpected token ‘point’ at line 61
Shader error in ‘Hidden/Vignetting’: syntax error: unexpected token ‘point’ at line 62
Shader error in ‘Hidden/Vignetting’: incorrect number of arguments to numeric-type constructor at line 68
How do I, can I compile?
Please tell me.
I am using the translation software.
thank you.
