    I am using the C4DNoise class to affect the shape of geometry in my plugin.  I know that in a material that the user has the option to adjust the brightness of the noise.  How is this achieved?  what aspect of the noise is being adjusted when the user changes the brightness?  Any help would be greatly appreciated.

    Thanks,

    Shawn

    I'm not sure but I think about this:
    The values are mapped. For example you're obtained Noisevalue is 0.7.
    You want to bright it up by 50 %. The Range of the noise changes for 0 - 1 to 0.5 - 1.
    Your new value would be 0.85

      
    //Pseudocode   
    brightness = 0.5   
    //valuerange   
    min = 0   
    max = 1   
    //noisevalue   
    value = noise.GetValue()   
    value = (value*(max-min-brightness)+min+brightness)
