Blob shadow projector is not projecting properly

I found a fix. Since I had an older project with these blob shadows and it worked there, I got the shader from that and replaced it with that. For some reason, the shader seemed to be broken.

Here's the shader code. Just replace it with the old shader code you already got.

 Shader "Projector/Multiply" {
     Properties{
         _ShadowTex("Cookie", 2D) = "gray" {}
         _FalloffTex("FallOff", 2D) = "white" {}
     }
     Subshader {
         Tags { "Queue" = "Transparent" }
         Pass {
             ZWrite Off
             ColorMask RGB
             Blend DstColor Zero
             Offset -1, -1
 
             CGPROGRAM
             #pragma vertex vert
             #pragma fragment frag
             #pragma multi_compile_fog
             #include "UnityCG.cginc"
 
             struct v2f {
                 float4 uvShadow : TEXCOORD0;
                 float4 uvFalloff : TEXCOORD1;
                 UNITY_FOG_COORDS(2)
                 float4 pos : SV_POSITION;
             };
 
             float4x4 _Projector;
             float4x4 _ProjectorClip;
 
             v2f vert(float4 vertex : POSITION)
             {
                 v2f o;
                 o.pos = mul(UNITY_MATRIX_MVP, vertex);
                 o.uvShadow = mul(_Projector, vertex);
                 o.uvFalloff = mul(_ProjectorClip, vertex);
                 UNITY_TRANSFER_FOG(o,o.pos);
                 return o;
             }
 
             sampler2D _ShadowTex;
             sampler2D _FalloffTex;
 
             fixed4 frag(v2f i) : SV_Target
             {
                 fixed4 texS = tex2Dproj(_ShadowTex, UNITY_PROJ_COORD(i.uvShadow));
                 texS.a = 1.0 - texS.a;
 
                 fixed4 texF = tex2Dproj(_FalloffTex, UNITY_PROJ_COORD(i.uvFalloff));
                 fixed4 res = lerp(fixed4(1,1,1,0), texS, texF.a);
 
                 UNITY_APPLY_FOG_COLOR(i.fogCoord, res, fixed4(1,1,1,1));
                 return res;
             }
             ENDCG
         }
     }
