Try to avoid casting shadows with Omni lights because they will use a lot more memory than a spotlight casting shadows. Omni lights are good for fill lights as well as for simulating certain practical light sources that have a brighter center and falloff evenly around that bright spot in all three axes. You could even use Omni lights for all three points in your three-point lighting system as seen here on the fruit still life scene. The scene has a nice soft feel. Skylight Skylight is a special 3ds Max light used with a special rendering method to quickly generate a scene rendered in a soft outdoor light. We will not be covering this more advanced lighting and rendering methodology however here is a quick introduction to the light itself. 424 chapter 10 3ds Max Lighting Figure shows a skylight high above the scene with the three spheres. It is created by simply selecting the Skylight button in the Create panel and clicking to place it in a viewport. The skylight s Skylight Parameters rollout is shown here. The skylight is used to create a soft global lighting to simulate light from the sky. This look is often seen with renders using Global Illumination or Radiosity. In these lighting rendering solutions the skylight creates a sky dome that sits around the objects in the scene. Light is emitted essentially from the entire surface area of the dome to cast an even light throughout the scene much as a sky lights an outdoor area. The rendering of a Skylight scene as shown in Figure is flat and bright. There is no definition because shadows are not enabled. Turning on shadows gives you a beautiful render as seen in Figure with soft shadows and contact shadows that really make the spheres look as if they are sitting outside on an afternoon day. Figure A skylight placed over the spheres and ground plane Figure The skylight flattens out the spheres and blows them out. .
