SpotCutoff Property

In This Topic

Gets/sets the value of the spot cutoff angle.

Syntax

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.
