stuck with fog 8-o

hi all :slight_smile:

I’m digging in this since this morning, and cannot figure what is the problem:

Here’s my shader :

Shader "Unlit/ambient_shado_nitghlights"
{
    Properties
    {
      _MainTex ("Texture", 2D) = "white" {}
      _LightTex ("Texture", 2D) = "black" {}
      _LightStrength("Lightmap strength",Float) = 1
         _Ambient_factor("Ambient dif. fact.", Float) = 1
          light_on_level("lights ON level", Range(0,1)) = 0.5
       
    }
    SubShader
    {
     Tags {"Queue"="Geometry" "RenderType"="Opaque" }
     LOD 100

     Pass
     {
         Tags {"LightMode"="ForwardBase"}       
         CGPROGRAM
         #pragma vertex vert
         #pragma fragment frag
         // make fog & shadows work
         #pragma multi_compile_fwdbase nolightmap nodirlightmap nodynlightmap novertexlight multi_compile_fog

         #include "UnityCG.cginc"
         #include "AutoLight.cginc"           
        
         struct appdata
         {
             float4 vertex : POSITION;
             float2 uv : TEXCOORD0;
         };

         struct v2f
         {
             float2 uv : TEXCOORD0;
             SHADOW_COORDS(1) // put shadows data into TEXCOORD1
             UNITY_FOG_COORDS(1)
             float4 pos : SV_POSITION;
         };

         sampler2D _MainTex;
         sampler2D _LightTex;
         float4 _MainTex_ST;
         half _Ambient_factor;
         half _LightStrength;
         half light_on_level;

         v2f vert (appdata v)
         {
             v2f o;
             o.pos = UnityObjectToClipPos(v.vertex);
             o.uv = TRANSFORM_TEX(v.uv, _MainTex);
             TRANSFER_SHADOW(o);
             UNITY_TRANSFER_FOG(o,o.pos);

             return o;
         }
        
        
         //***************************************
         //
         // les calculs d'un éclairage Ambient
         //
         //***************************************
         inline half4 AmbientLight(half4 color,half4 shad)
         {

            half4 c;
            c.rgb = (UNITY_LIGHTMODEL_AMBIENT.rgb*color.rgb*shad);
            return c;
         }
         //========================================================================
        
        
         fixed4 frag (v2f i) : SV_Target
         {
            // sample the texture
            fixed4 c = tex2D(_MainTex, i.uv);
            fixed4 nite_lights = tex2D(_LightTex, i.uv)*tex2D(_LightTex, i.uv);
            
            // compute shadow attenuation (1.0 = fully lit, 0.0 = fully shadowed)
            fixed shadow = SHADOW_ATTENUATION(i)/2+0.5;
            fixed ON_OFF = (UNITY_LIGHTMODEL_AMBIENT.g > light_on_level)?0:1;
           
            half4 col = AmbientLight(c,shadow)*_Ambient_factor+c*(nite_lights * _LightStrength)*ON_OFF;               
            col.a = 1;
       
            // apply fog
            UNITY_APPLY_FOG(i.fogCoord, 1);//col);
            return col;
         }
         ENDCG
      }
      // shadow casting support
      UsePass "Legacy Shaders/VertexLit/SHADOWCASTER"

   }
}

And here’s the result:

It’s just perfectly what i need but the for don’t apply…

Anyone could please tell me what i’m doing wrong ?

Thanks in advance and happy unitying !

Stuff that starts with multi_compile need to be their own #pragma lines.

#pragma multi_compile_fwdbase nolightmap nodirlightmap nodynlightmap novertexlight
#pragma multi_compile_fog

Awwww !!! this was so simple XD

Thanks a lot @bgolus ! :slight_smile:

Happy unitying !
