    Syntax
    'Declaration
 

    Public Property SpotCutoff As System.Single
    'Usage
 

    Dim instance As NSpotLightSource
Dim value As System.Single
 
instance.SpotCutoff = value
 
value = instance.SpotCutoff
    public System.float SpotCutoff {get; set;}
    Remarks
    The spot cutoff angle is the maximum value of the angle between the vector defined from the light position and the light direction and the vector defined from the light position and the object. If the value of this angle is bigger than the SpotCutoff the light becomes completely masked. With the help of this property you can achieve directed lights. For example a regular torch has a SpotCuttoff angle of around 45 degrees.
