                   often struggle with the same problem of too much or too little light. This chapter

                   Lighting plays a critical part of any Max scene. Understanding the basics of light-  Using the Sunlight and

                   scenes. Most Max scenes typically use one of two types of lighting: natural light
                   or artificial light. Natural light is used for outside scenes and uses the sun and   Using the Volume light effect

                   Natural and artificial light
                   Natural light is best created using lights that have parallel light rays coming from a
                   single direction: You can create this type of light using a Direct Light. The intensity
                   of natural light is also dependent on the time, date, and location of the sun: You
                   can control this intensity precisely using Max’s Sunlight or Daylight systems.
                   The weather can also make a difference in the light color. In clear weather, the
                   color of sunlight is pale yellow; in clouds, sunlight has a blue tint; and in dark,
                   stormy weather, sunlight is dark gray. The colors of light at sunrise and sunset
                   are more orange and red. Moonlight is typically white.
