Surface shader vertex function 'SplatmapVert' not found
I am trying to combine two working shaders into one new one but i get the error as seen in title. I am not sure why SplatmapVert is acceptable in the terrain shader i am taking it from but cannot be found when used in the combined shader. Here is the line i want to copy over: #pragma surface surf Lambert vertex:SplatmapVert finalcolor:SplatmapFinalColor finalprepass:SplatmapFinalPrepass finalgbuffer:SplatmapFinalGBuffer noinstancing
Is it as simple as missing some reference somewhere? I am new to shaders so i worry it may be.
See below for (1)the terrain shader, (2)the FOW shader and (3)my attempt at combining them.
The terrain shader (with the pragma line i want):
Shader "Nature/Terrain/Diffuse" {
Properties {
[HideInInspector] _Control ("Control (RGBA)", 2D) = "red" {}
[HideInInspector] _Splat3 ("Layer 3 (A)", 2D) = "white" {}
[HideInInspector] _Splat2 ("Layer 2 (B)", 2D) = "white" {}
[HideInInspector] _Splat1 ("Layer 1 (G)", 2D) = "white" {}
[HideInInspector] _Splat0 ("Layer 0 (R)", 2D) = "white" {}
[HideInInspector] _Normal3 ("Normal 3 (A)", 2D) = "bump" {}
[HideInInspector] _Normal2 ("Normal 2 (B)", 2D) = "bump" {}
[HideInInspector] _Normal1 ("Normal 1 (G)", 2D) = "bump" {}
[HideInInspector] _Normal0 ("Normal 0 (R)", 2D) = "bump" {}
// used in fallback on old cards & base map
[HideInInspector] _MainTex ("BaseMap (RGB)", 2D) = "white" {}
[HideInInspector] _Color ("Main Color", Color) = (1,1,1,1)
}

void surf(Input IN, inout SurfaceOutput o)
{
half4 splat_control;

o.Albedo = mixedDiffuse.rgb;
o.Alpha = weight;
}

// TODO: Seems like "#pragma target 3.0 _TERRAIN_NORMAL_MAP" can't fallback correctly on less capable devices?
// Use two sub-shaders to simulate different features for different targets and still fallback correctly.
SubShader { // for sm3.0+ targets

#pragma target 3.0
#pragma multi_compile __ _TERRAIN_NORMAL_MAP

Dependency "AddPassShader" = "Hidden/TerrainEngine/Splatmap/Diffuse-AddPass"
Dependency "BaseMapShader" = "Diffuse"
Dependency "Details0" = "Hidden/TerrainEngine/Details/Vertexlit"

Dependency "Details2" = "Hidden/TerrainEngine/Details/BillboardWavingDoublePass"

The Fog of War shader i am trying to combine with it:
Shader "Fog Of War/Terrain" {
Properties {
_MainTex ("Base (RGB)", 2D) = "white" {}
}
SubShader {
Tags { "RenderType"="Opaque" }
LOD 200
CGPROGRAM
#pragma surface surf Lambert
#include "FOWIncludes.cginc"
sampler2D _MainTex;
sampler2D _FOWTex;
float4 _FOWTex_ST;
struct Input {
float2 uv_MainTex;
float3 worldPos;
};
void surf (Input IN, inout SurfaceOutput o) {
half4 c = tex2D(_MainTex, IN.uv_MainTex);
half4 fow = tex2D(_FOWTex, TRANSFORM_TEX(IN.worldPos.xz, _FOWTex));
half4 t = TransformColourFOWAO(c, fow);
o.Albedo = t.rgb;
o.Alpha = t.a;
}
ENDCG
}
FallBack "Diffuse"
}
The combined result so far (should be the same effect as the FOW one above):
Shader "Nature/Terrain/FOW"
{
Properties
{
[HideInInspector] _Control ("Control (RGBA)", 2D) = "red" {}
[HideInInspector] _Splat3 ("Layer 3 (A)", 2D) = "white" {}
[HideInInspector] _Splat2 ("Layer 2 (B)", 2D) = "white" {}
[HideInInspector] _Splat1 ("Layer 1 (G)", 2D) = "white" {}
[HideInInspector] _Splat0 ("Layer 0 (R)", 2D) = "white" {}
[HideInInspector] _Normal3 ("Normal 3 (A)", 2D) = "bump" {}
[HideInInspector] _Normal2 ("Normal 2 (B)", 2D) = "bump" {}
[HideInInspector] _Normal1 ("Normal 1 (G)", 2D) = "bump" {}
[HideInInspector] _Normal0 ("Normal 0 (R)", 2D) = "bump" {}
[HideInInspector] _MainTex ("BaseMap (RGB)", 2D) = "white" {}
[HideInInspector] _Color ("Main Color", Color) = (1,1,1,1)
