WebGL displacement shader doesn't work in build
I'm working on a displacement and tessellation shader for a WebGL project. I have isolated it as the main reason why the build doesn't work but don't know why it doesn't work. Here is the shader itself:
Shader "Custom/Digsite_v2"
{
Properties
{
_Tess ("Tesselation", Range(1,32)) = 4
_Color ("Soil", Color) = (1,1,1,1)
_SoilTex("Soil (RGB)", 2D) = "white" {}
_GroundColor("Ground", Color) = (1,1,1,1)
_GroundTex("Ground (RGB)", 2D) = "white" {}
_Splat("Splat Map", 2D) = "black"{}
_Displacement("Displacement", Range(0,1.0)) = 0.3
_Glossiness ("Smoothness", Range(0,1)) = 0.5
_Metallic ("Metallic", Range(0,1)) = 0.0
}
SubShader
{
Tags { "RenderType"="Opaque" }
LOD 200

// Physically based Standard lighting model, and enable shadows on all light types
#pragma surface surf Standard fullforwardshadows vertex:disp tessellate:tessFixed

float4 vertex : POSITION;
float4 tangent : TANGENT;

};
float _Tess;

}
sampler2D _Splat;

void disp(inout appdata v)
{
float d = tex2Dlod(_Splat, float4(v.texcoord.xy,0,0)).r * _Displacement;
v.vertex.xyz -= v.normal * d;
//v.vertex.xyz += v.normal * _Displacement;
}

void surf (Input IN, inout SurfaceOutputStandard o)
{

half amount = tex2Dlod(_Splat, float4(IN.uv_Splat, 0, 0)).r;

o.Albedo = c.rgb;
// Metallic and smoothness come from slider variables
o.Metallic = _Metallic;
o.Smoothness = _Glossiness;
o.Alpha = c.a;
}

FallBack "Diffuse"
