Unity_URPShader_HLSL_색깔

색상을 바꾸는 것은 간단합니다.

#pragma fragment frag 에서 정의한 frag()함의 값을 반환함으로써 색상을 바꿀 수 있습니다.

 

 

Shader "StudySRP/Catlike1"
{
	Properties{}

	SubShader{
		Pass {

변수로 색상제어하기

Properties에 추가하고 사용한다고 선언한 뒤 사용하면 됩니다.

Properties {
   _BaseColor("Color", Color) = (1.0, 1.0, 1.0, 1.0)
}

float4 _BaseColor;

 

Shader "StudySRP/Catlike1"
{
	Properties{
	   _BaseColor("Color", Color) = (1.0, 1.0, 1.0, 1.0)
	}
