I work in standard surface shader but I d’ont know to add HDR in shader like a standard shader.
current standard shader
Shader "Custom/CullingShader"
{
Properties
{
_Color ("Color", Color) = (1,1,1,1)
_MainTex ("Albedo (RGB)", 2D) = "white" {}
_Glossiness ("Smoothness", Range(0,1)) = 0.5
_Metallic ("Metallic", Range(0,1)) = 0.0
}
SubShader
{
Tags { "RenderType"="Opaque" }
LOD 200
CGPROGRAM
// Physically based Standard lighting model, and enable shadows on all light types
#pragma surface surf Standard fullforwardshadows
// Use shader model 3.0 target, to get nicer looking lighting
#pragma target 3.0
sampler2D _MainTex;
struct Input
{
float2 uv_MainTex;
float3 worldPos;
};
half _Glossiness;
half _Metallic;
fixed4 _Color;
float _IsActiveCulling;
float4 _MyPlanePos;
float4 _MyPlaneNormal;
// Add instancing support for this shader. You need to check 'Enable Instancing' on materials that use the shader.
// See https://docs.unity3d.com/Manual/GPUInstancing.html for more information about instancing.
// #pragma instancing_options assumeuniformscaling
UNITY_INSTANCING_BUFFER_START(Props)
// put more per-instance properties here
UNITY_INSTANCING_BUFFER_END(Props)
void surf (Input IN, inout SurfaceOutputStandard o)
{
// Albedo comes from a texture tinted by color
fixed4 c = tex2D (_MainTex, IN.uv_MainTex) * _Color;
o.Albedo = c.rgb;
// Metallic and smoothness come from slider variables
o.Metallic = _Metallic;
o.Smoothness = _Glossiness;
o.Alpha = c.a;
if (_IsActiveCulling == 1.0f)
{
float3 planeRelativeCamPos = _WorldSpaceCameraPos - _MyPlanePos.xyz;
float planeCamDist = dot(planeRelativeCamPos, _MyPlaneNormal.xyz);
float3 planeRelativePixelPos = IN.worldPos - _MyPlanePos.xyz;
float planePixelDist = 0.0f;
if (planeCamDist >= 0.0f)
planePixelDist = dot(planeRelativePixelPos, _MyPlaneNormal.xyz);
else
planePixelDist = dot(planeRelativePixelPos, -_MyPlaneNormal.xyz);
clip(-planePixelDist);
}
// o.Albedo = c.rgb * 0.5f;
}
ENDCG

FallBack "Diffuse"
