So im trying to make some sort of distortion. Everything looks fine with perspective camera,but doesnt work with 2D/ortographic camera.
Here`s my shader.
Shader"Effects/Distortion/CullBack+1"{
Properties{
_Color("Main Color",Color)=(1,1,1,1)
_MainTex("Base (RGB) Gloss (A)",2D)="black"{}
_BumpMap("Normalmap",2D)="bump"{}
_ColorStrength("Color Strength",Float)=1
_BumpAmt("Distortion [0-100]", range (0,100))=10
}
SubShader{
Tags{"Queue"="Transparent+1""RenderType"="Transperent"}
GrabPass{}
LOD 200
ZWriteOn
CullBack
CGPROGRAM
#pragma surface surf Lambert alpha vertex:vert
sampler2D _MainTex;
sampler2D _BumpMap;

float4 _GrabTexture_TexelSize;
float4 _Color;
structInput{
float2 uv_MainTex;
float2 uv_BumpMap;
float4 proj : TEXCOORD0;
};
void vert (inout appdata_full v,outInput o){
UNITY_INITIALIZE_OUTPUT(Input,o);
float4 oPos = mul(UNITY_MATRIX_MVP, v.vertex);
#if UNITY_UV_STARTS_AT_TOP
float scale =-1.0;
#else
float scale =1.0;
#endif
o.proj.xy =(float2(oPos.x, oPos.y*scale)+ oPos.w)*0.5;
o.proj.zw = oPos.zw;
}
void surf (Input IN, inout SurfaceOutput o){
o.Normal=UnpackNormal(tex2D(_BumpMap, IN.uv_BumpMap));
half2 offset = o.Normal.rg *_BumpAmt*_GrabTexture_TexelSize.xy;
IN.proj.xy = offset * IN.proj.z + IN.proj.xy;
half4 col = tex2Dproj(_GrabTexture, UNITY_PROJ_COORD(IN.proj));
fixed4 tex = tex2D(_MainTex, IN.uv_MainTex)*_Color;
o.Emission= col.xyz + tex*_ColorStrength;
o.Alpha=_Color.a;
}
ENDCG
