3.1.1. MPD PowerSlider and IntRange

These drawers are quite useful when working with numerical ranges and precision. On the one hand, we have the PowerSlider, which allows us to generate a non-linear slider with curve control. 

Its syntax is as follows:

[PowerSlider(3.0)] _PropertyName ("Display name", Range (0.01, 1)) = 0.08

On the other hand, we have the IntRange which, as its name says, adds a numerical range of integer values. 

Its syntax is as follows:

[IntRange] _PropertyName ("Display name", Range (0, 255)) = 100

Note that, if we want to use these properties within our shader, they have to be declared within the CGPROGRAM in the same way as a conventional property. To understand how to use it, we will do the following operation:

Shader “InspectorPath / shaderName”
{
    Properties 
    {
        // declare drawer 
        [PowerSlider(3.0)] 
            _Brightness (“Brightness", Range (0.01, 1)) = 0.08

        [IntRange] 
            _Samples ("Samples", Range (0, 255)) = 100
    } 
    SubShader
    {
        Pass
        {
            CGPROGRAM
            ...
            // generate connection variables 
            float _Brightness;
            int _Samples;
            ...
            ENDCG
        }
    }
}

In the example above, we declare a PowerSlider called _Brightness and an IntRange called _Samples. Finally, using the same names, we generate our connection variables within the CGPROGRAM.
