Shader "Custom/Transparent"

        _MainTex ("Albedo (RGB)", 2D) = "white" {}
        _Glossiness ("Smoothness", Range(0,1)) = 0.5
        _Metallic ("Metallic", Range(0,1)) = 0.0
    }
    SubShader
    {
        Tags {"Queue" = "Transparent" "RenderType"="Transparent" }
        LOD 200
   
        CGPROGRAM
