How to match lighting between Deferred Shader and Forward Shader

Unity Engine
1

In the following image you can see that certain parts of my world are illuminated differently. Although both shaders are almost the same. There seems to be one major difference: One shader uses forward rendering where the other is based on deferred shading.

Do their lighting equations differ? If so, what can I do to make them match? If not, what am I doing wrong?

Here you can see the code for both shaders in use:

Forward Shader:

Shader "Custom/WorldAlpha"
{
    Properties
    {
        _Color ("Main Color", Color)          = (0.5,0.5,0.5,1)
        _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
    }

    SubShader
    {
        Tags
        {
            "Queue"           = "Transparent"
            "IgnoreProjector" = "True"
            "RenderType"      = "Transparent"
        }

        Fog
        {
            Mode Off
        }

        LOD 200

        CGPROGRAM
        #pragma surface surf Lambert alpha nofog

        sampler2D _MainTex;
        fixed4 _Color;

        struct Input
        {
            float2 uv_MainTex;
            float4 color : COLOR;
            float3 worldNormal;
            float3 worldPos;
        };

        void surf(Input IN, inout SurfaceOutput o)
        {
            o.Albedo   = float3(0.3,.5,0.3);
            o.Alpha  = 1;
        }

        ENDCG
    }

    Fallback "Transparent/VertexLit"
}

Deferred Shader:

Shader "Custom/World"
{
    Properties
    {
        _Color ("Main Color", Color)          = (0.5,0.5,0.5,1)
        _MainTex ("Base (RGB) Trans (A)", 2D) = "white" {}
        _Cutoff ("Alpha cutoff", Range(0,1))  = 0.5
    }

    SubShader
    {
        Tags
        {
            "Queue"           = "AlphaTest"
            "IgnoreProjector" = "True"
            "RenderType"      = "TransparentCutout"
        }

        Fog
        {
            Mode Off
        }

        LOD 200

        CGPROGRAM
        #pragma surface surf Lambert alphatest:_Cutoff nofog noforwardadd novertexlights nolightmap exclude_path:forward exclude_path:prepass nometa nodirlightmap nodynlightmap

        sampler2D _MainTex;
        fixed4 _Color;

        struct Input
        {
            float2 uv_MainTex;
            float4 color : COLOR;
            float3 worldNormal;
            float3 worldPos;
        };

        void surf(Input IN, inout SurfaceOutput o)
        {
            o.Albedo   = float3(0.3,.5,0.3);
            o.Alpha    = 1;
        }

        ENDCG
    }

    Fallback "Transparent/Cutout/VertexLit"
}

Bump…

Does noone know how to accomplish this? :frowning: Am I doing something wrong?
