public int cullingMask ;

설명

This is used to light certain objects in the Scene selectively.

A GameObject will only be illuminated by a light if that light's cullingMask/ includes the layer chosen for the GameObject (ie, the mask bit for the layer must be set to 1 for the object to receive any light). See Layers for more information about layer masking. See Also: Light component.
