Point The point light produces omnidirectional rays originating from the light icon. Point

lights are similar to lightbulbs or other sources that have a small, physically spherical shape.

Spot The Maya spot light re-creates a spotlight found on a stage or motion picture set.

Thanks to its conical shape, the spot light produces naturally divergent rays. In general,

the light can emulate artiﬁ cial sources that are close to the subject. Because of the spot

light’s cone, it has an identiﬁ able falloff from 100 percent to 0 percent intensity. The size

of the cone is controlled by the Cone Angle attribute. The softness of the cone edge is set

by the Penumbra attribute, which is 0 by default. Note that the scale of the spot light icon

does not affect its light quality.
