3ds max Lighting Adjusting light distribution Back up in the distribution types, the options that we have available here will depend upon which light shape we currently have chosen. So for a rectangle, I can choose any of these four options. The ones we've seen so far are the default uniform spherical, the current is uniform diffuse, the photometric web distribution type allows you to load in a manufacturer's lighting definition file. There's also a spotlight distribution. We'll take a look at that in the following movie. For a rectangle shape, once again, we should choose uniform diffuse. That's how to choose a light distribution type for a particular light shape.
