Is it possible to create a depth render of scene using a replacement shader?
I want to create a shader that is set as a replacement shader to the camera and renders the scene's depth much like what is seen in this image.
I tried the depth shader below but it my results seem to be wrong as seen in this image
Shader "Hidden/DepthShader"
{
Properties
{
_MainTex("Base (RGB)", 2D) = "white" {}
}
SubShader
{
Pass
{
CGPROGRAM
#pragma vertex vert
#pragma fragment frag
#include "UnityCG.cginc"
uniform sampler2D _MainTex;
uniform sampler2D _CameraDepthTexture;
uniform half4 _MainTex_TexelSize;
struct input
{
float4 pos : POSITION;
half2 uv : TEXCOORD0;
};
struct output
{
float4 pos : SV_POSITION;
half2 uv : TEXCOORD0;
};
output vert(input i)
{
output o;
o.pos = UnityObjectToClipPos(i.pos);
o.uv = MultiplyUV(UNITY_MATRIX_TEXTURE0, i.uv);
#if UNITY_UV_STARTS_AT_TOP
if (_MainTex_TexelSize.y < 0)
o.uv.y = 1 - o.uv.y;
#endif
return o;
}
fixed4 frag(output o) : COLOR
{
float depth = UNITY_SAMPLE_DEPTH(tex2D(_CameraDepthTexture, o.uv));
depth = pow(Linear01Depth(depth), 0.25);
return depth;
}
ENDCG
}
}
}
Any ideas as to what is going wrong here?
