Hudmask + blur shader join

[bover]

Hi, im using hudmask shader from https://wiki.multitheftauto.com/wiki/Shader_examples, also have a blur shader that i found somewhere on internet. I want to join those both shaders to make a shader that blurs screen source and clamp that on mask that i provide. Already connected both shaders, blur works but mask not. I were trying a lot of things but I'm not specialist of HLSL. Anyone can help?

Shader:

#include "tex_matrix.fx"

texture screenSource;
texture maskTexture;
float factor;

float2 gUVPrePosition = float2( 0, 0 );
float2 gUVScale = float( 1 );
float2 gUVScaleCenter = float2( 0.5, 0.5 );
float gUVRotAngle = float( 0 );
float2 gUVRotCenter = float2( 0.5, 0.5 );
float2 gUVPosition = float2( 0, 0 );

float3x3 getTextureTransform() {
    return makeTextureTransform(gUVPrePosition, gUVScale, gUVScaleCenter, gUVRotAngle, gUVRotCenter, gUVPosition);
};

sampler Sampler0 = sampler_state {
    Texture = screenSource;
    AddressU = Clamp;
    AddressV = Clamp;
};

struct PSInput {
    float2 TexCoord : TEXCOORD0;
};

float4 PixelShader_Background(PSInput PS) : COLOR0 {
	float4 sum = tex2D(Sampler0, PS.TexCoord);
	for (float i = 1; i < 3; i++) {
		sum += tex2D(Sampler0, float2(PS.TexCoord.x, PS.TexCoord.y + (i * factor)));
		sum += tex2D(Sampler0, float2(PS.TexCoord.x, PS.TexCoord.y - (i * factor)));
		sum += tex2D(Sampler0, float2(PS.TexCoord.x - (i * factor), PS.TexCoord.y));
		sum += tex2D(Sampler0, float2(PS.TexCoord.x + (i * factor), PS.TexCoord.y));
	}
	sum /= 9;
	sum.a = 1.0;
	return sum;
}

technique complercated {
    pass P0 {
        PixelShader = compile ps_2_0 PixelShader_Background();
    }
}

technique simple {
    pass P0 {
        Texture[0] = screenSource;
        
        TextureTransform[0] = getTextureTransform();
        TextureTransformFlags[0] = Count2;
        AddressU[0] = Clamp;
        AddressV[0] = Clamp;

        ColorOp[0] = Modulate;
        ColorArg1[0] = Texture;
        ColorArg2[0] = Diffuse;

        AlphaOp[0] = Modulate;
        AlphaArg1[0] = Texture;
        AlphaArg2[0] = Diffuse;
     
        Texture[1] = maskTexture;
        TexCoordIndex[1] = 0;
        AddressU[1] = Clamp;
        AddressV[1] = Clamp;

        ColorOp[1] = SelectArg1;
        ColorArg1[1] = Current;

        AlphaOp[1] = Modulate;
        AlphaArg1[1] = Current;
        AlphaArg2[1] = Texture;

        ColorOp[2] = Disable;
        AlphaOp[2] = Disable;
    }
}

tex_matrix.fx:

//

//-------------------------------------------
// Returns a translation matrix
//-------------------------------------------
float3x3 makeTranslationMatrix ( float2 pos )
{
    return float3x3(
                    1, 0, 0,
                    0, 1, 0,
                    pos.x, pos.y, 1
                    );
}

float3x3 makeRotationMatrix ( float angle )
{
    float s = sin(angle);
    float c = cos(angle);
    return float3x3(
                    c, s, 0,
                    -s, c, 0,
                    0, 0, 1
                    );
}


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

                    0, scale.y, 0,
                    0, 0, 1
                    );
}


//-------------------------------------------
// Returns a combined matrix of doom
//-------------------------------------------
float3x3 makeTextureTransform ( float2 prePosition, float2 scale, float2 scaleCenter, float rotAngle, float2 rotCenter, float2 postPosition )
{
    float3x3 matPrePosition = makeTranslationMatrix( prePosition );
    float3x3 matToScaleCen = makeTranslationMatrix( -scaleCenter );
    float3x3 matScale = makeScaleMatrix( scale );
    float3x3 matFromScaleCen = makeTranslationMatrix( scaleCenter );
    float3x3 matToRotCen = makeTranslationMatrix( -rotCenter );
    float3x3 matRot = makeRotationMatrix( rotAngle );
    float3x3 matFromRotCen = makeTranslationMatrix( rotCenter );
    float3x3 matPostPosition = makeTranslationMatrix( postPosition );

    float3x3 result =
                    mul(
                    mul(
                    mul(
                    mul(
                    mul(
                    mul(
                    mul(
                        matPrePosition
                        ,matToScaleCen)
                        ,matScale)
                        ,matFromScaleCen)
                        ,matToRotCen)
                        ,matRot)
                        ,matFromRotCen)
                        ,matPostPosition)
                    ;
    return result;
}

 

Shader usage:

local screenSource = dxCreateScreenSource(1920, 1080)
local shader = dxCreateShader("blurMask.fx")
local texture = dxCreateTexture("panel.png")
local renderTarget = dxCreateRenderTarget(539, 539, true)
dxSetShaderValue(shader, 'screenSource', screenSource)
dxSetShaderValue(shader, 'factor', 0.007)
dxSetShaderValue(shader, 'maskTexture', texture)

function renderScreen()
    dxUpdateScreenSource(screenSource)

    dxSetRenderTarget(renderTarget, true)
        dxDrawImage(-(1920/2-(539/2)), -(1080/2-(539/2)), 1920, 1080, screenSource)
    dxSetRenderTarget()

    dxDrawImage(0, 0, 539, 539, texture)
    dxSetShaderValue(shader, 'screenSource', renderTarget)
    
    for intensity = 0, 4 do
        dxSetShaderValue(shader, 'factor', 0.0080 * 1 + (intensity / 4 * 0.001 * 1));
    end

    dxDrawImage(1920/2-(539/2), 1080/2-(539/2), 539, 539, shader)
end 
addEventHandler('onClientRender', root, renderScreen)

 

Effect I've got:

Expected effect should mask the blur for a texture i provide (this circle that is rendered on the left top side of screen)
