Need Reflection Strength

Unity Engine
1

I use mirrorreflection shader for reflection and it work very nice but the reflection strength is high.
I want to control the reflection strength, i m new about the shader script and i m try to add alpha channel but its not work.
How i control the reflection strength ?:face_with_spiral_eyes:

change the shader so it uses an the alpha of a color to blend between a primary texture and the mirror reflection

Shader "FX/Mirror Reflection" {

Properties {
	 _Color ("Alpha Fade", Color) = (1,1,1,0.5)
    _MainTex ("Base (RGB)", 2D) = "white" {}
    _ReflectionTex ("Reflection", 2D) = "white" { TexGen ObjectLinear }
}

// two texture cards: full thing
Subshader {
    Pass {
        SetTexture[_MainTex] { combine texture }
        SetTexture[_ReflectionTex] { 
        	constantColor[_Color]
        	matrix [_ProjMatrix] combine texture lerp(constant) previous 
        	}
    }
}

// fallback: just main texture
Subshader {
    Pass {
        SetTexture [_MainTex] { combine texture }
    }
}

}
