HLSL-Multi-Texturierung mit Nebelproblem in Direct3D

Question

Ich versuche, eine Multi-Texturierung und Nebel auf einige Gelände in meiner Demo zu implementieren, aber anscheinend bin ich falsch irgendwo, weil die Texturierung nicht sichtbar ist, die einzige Sache, die gerendert wird, ist die Nebelfarbe in das Terrain.

Keinerlei Anzeichen einer Texturierung.

Hier ist die fx-Datei:

//------------------------------------
//Stuff for the Terrain
uniform extern float4x4 MatVP;
uniform extern float3  SunPos;
uniform extern texture Tex0;
uniform extern texture Tex1;
uniform extern texture Tex2;
uniform extern texture TexGS;
uniform extern float3  EyePos;

//------------------------------------

sampler sTex0 = sampler_state
{
    Texture = <Tex0>;
    MagFilter = LINEAR;
    MinFilter = ANISOTROPIC;
    MaxAnisotropy = 8;
    MipFilter = LINEAR;
    AddressU = WRAP;
    AddressV = WRAP;
};

sampler sTex1 = sampler_state
{
    Texture = <Tex1>;
    MagFilter = LINEAR;
    MinFilter = ANISOTROPIC;
    MaxAnisotropy = 8;
    MipFilter = LINEAR;
    AddressU = WRAP;
    AddressV = WRAP;
};
sampler sTex2 = sampler_state
{
    Texture = <Tex2>;
    MagFilter = LINEAR;
    MinFilter = ANISOTROPIC;
    MaxAnisotropy = 8;
    MipFilter = LINEAR;
    AddressU = WRAP;
    AddressV = WRAP;
};
sampler sTexGS = sampler_state
{
    Texture = <TexGS>;
    MinFilter = LINEAR;
    Magfilter = LINEAR;
    Mipfilter = POINT;
    AddressU = WRAP;
    AddressV = WRAP;
};

const float3 FogColor = {0.5f, 0.5f, 0.5f};
const float  FogStart = 10.0f;
const float  FogRange = 200.0f;

struct vOut {
    float4 PosH            : POSITION0;
    float2 cTexTiled    : TEXCOORD0;
    float2 cTexNonTiled : TEXCOORD1;
    float shade            : TEXCOORD2;
    float FogSaturate    : TEXCOORD3;
};

//------------------------------------
vOut VS_Def(float3 PosW : POSITION0
 , float3 NormW : NORMAL0
 , float2 cTex : TEXCOORD0)
{
    vOut V = (vOut)0;

    V.PosH = mul(float4(PosW, 1.0f), MatVP);

    float3 SunVec = normalize(SunPos - EyePos);
    V.shade = saturate(max(0.0f, dot(NormW, SunVec)) + 0.25f);

    float Dist = distance(PosW, EyePos);
    V.FogSaturate = saturate((Dist - FogStart)/FogRange);

    V.cTexTiled = cTex * 16.0f;
    V.cTexNonTiled = cTex;
    return V;
}

float4 PS_Def(float2 cTexTiled : TEXCOORD0
, float2 cTexNonTiled : TEXCOORD1
, float shade : TEXCOORD2
, float FogSaturate : TEXCOORD3): COLOR
{
    float3 Tex0 = tex2D(sTex0, cTexTiled).rgb;
    float3 Tex1 = tex2D(sTex1, cTexTiled).rgb;
    float3 Tex2 = tex2D(sTex2, cTexTiled).rgb;
    float3 TexGS= tex2D(sTexGS,cTexNonTiled).rgb;

    float inv = 1 / (TexGS.r + TexGS.g + TexGS.b);
    Tex0 *= TexGS.r * inv;
    Tex1 *= TexGS.g * inv;
    Tex2 *= TexGS.b * inv;
    float3 TexColor = (Tex0 + Tex1 + Tex2) * shade;
    float3 FinalColor = lerp(TexColor, FogColor, FogSaturate);

    return float4(FinalColor, 1.0f);
}

//-----------------------------------
technique DefTech
{
    pass p0 
    {        
        VertexShader = compile vs_2_0 VS_Def();
        PixelShader = compile ps_2_0 PS_Def();

    }
}

wie Sie sehen können, ist die Nebelfarbe grau, und das ist alles, was ich bekomme. Es ist sehr deprimierend.
