[Solved] Both Textures and Sampler Data are the same in PostProcessing Shader

Graphics

Hello Everyone,
I am trying to convert my game Clean’Em Up from XNA 4 to MonoGame. I had a bloomeffect shader used but when I am trying to used it both sampler0 and sampler1 use the same texture sent in the SpriteBatch regarding of anything attached.

Here is the shader file code:

// Pixel shader combines the bloom image with the original
// scene, using tweakable intensity levels and saturation.
// This is the final step in applying a bloom postprocess.

#define DECLARE_TEXTURE(Name, index) \
    Texture2D<float4> Name : register(t##index); \
    sampler Name##Sampler : register(s##index)

#define SAMPLE_TEXTURE(Name, texCoord)  Name.Sample(Name##Sampler, texCoord)

DECLARE_TEXTURE(BloomSampler, 0);
DECLARE_TEXTURE(BaseSampler, 1);

float BloomIntensity;
float BaseIntensity;

float BloomSaturation;
float BaseSaturation;

// Helper for modifying the saturation of a color.
float4 AdjustSaturation(float4 color, float saturation)
{
    // The constants 0.3, 0.59, and 0.11 are chosen because the
    // human eye is more sensitive to green light, and less to blue.
    float grey = dot(color, float3(0.3, 0.59, 0.11));

    return lerp(grey, color, saturation);
}

float4 PixelShaderFunction(float4 position: POSITION0, float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0
{
    // Look up the bloom and original base image colors.
    float4 bloom = SAMPLE_TEXTURE(BloomSampler, texCoord);
    float4 base = SAMPLE_TEXTURE(BaseSampler, texCoord);

    // Adjust color saturation and intensity.
    bloom = AdjustSaturation(bloom, BloomSaturation) * BloomIntensity;
    base = AdjustSaturation(base, BaseSaturation) * BaseIntensity;

    // Darken down the base image in areas where there is a lot of bloom,
    // to prevent things looking excessively burned-out.
    base *= (1 - saturate(bloom));

    // Combine the two images.
    return base + bloom;
}


technique BloomCombine
{
    pass Pass1
    {
        #if SM5
	    PixelShader = compile ps_5_0 PixelShaderFunction();
	#elif SM4
        PixelShader = compile ps_4_0_level_9_3 PixelShaderFunction();
	#elif SM3
	PixelShader = compile ps_3_0 PixelShaderFunction();
	#else
	PixelShader = compile ps_2_0 PixelShaderFunction();
	#endif
    }
}

And in the C# Code I write these lines

 GraphicsDevice.Textures[1] = sceneRenderTarget;
 spriteBatch.Begin(0, BlendState.Opaque, null, null, null, effect);
 spriteBatch.Draw(renderTarget1, new Rectangle(0, 0, width, height), Color.White);
 spriteBatch.End();

renderTarget1 is blurred version of the screen, I checked it by drawing it without the effect and sceneRenderTarget contains the game screen

when I played in the shader file and returned only base or bloom without decreasing the its saturation for the base both are the same image but base is just more black and white

so what is the wrong with the code?

Solved it by setting the parameter with my hands while playing around with the code

parameters["BaseSampler"].SetValue(sceneRenderTarget);

instead of

GraphicsDevice.Textures[1] = sceneRenderTarget;

I think it need to be fixed
