Definition

Visual Basic Public Property Falloff As Single
C# public float Falloff { get; set; }

        void set(float value);

Property Value

System.Single
Value that indicates the decrease in illumination.

This property is read/write. 

Remarks

The effect of falloff, the light attenuation between a spotlight's inner and outer cones, on the lighting is subtle. Furthermore, a small performance penalty is incurred by shaping the falloff curve. For these reasons, most developers set this value to 1.0.

Exceptions

InvalidCallException

The property value is invalid.
