Lights and light studios can be taken directly from the archives and applied to the model by dropping them into the palette. These can then be repositioned as needed.
The Recommended archive contains five lights (Ambient, Distant, Eye, Point, and Spot), a Standard Light Studio, an Environment Light Studio, an Environment folder containing two Environment lights utilizing HDRI-based light sources (see Image-based Lighting for more information), and an Exterior folder with different city locations around the world, each containing three light studios (Clear Sky, Overcast Sky and Sun Study).
If you are creating an external render of a building, for example, then you may find that one of the Environment light studios can give a very realistic effect, using image-based lighting to light the model. Exterior light studios may also give you the effect you require. These do use physically accurate lights, however, which generally take longer to render the scene.
Alternatively, you may prefer to use the Standard Light Studio as a starting point and build up your lighting from there, adding combinations of the basic recommended lights to create the desired effect.
The Standard archive contains a Default Eye Light studio (which is effectively rendering with a head light); an Environmental folder; a folder of Exterior light studios, which predominantly consists of light studios that use a number of lights to replicate the effect of a Sky light. Not using physically accurate lights means, you don’t have to turn on Auto Exposure (see Auto Exposure), which can negatively impact on the basic recommended light settings; a folder of Interior light studios for use in internal scenes; a folder of Object light studios which are best suited to lighting smaller models, such as a vehicle or piece of machinery, for example; and a folder of Projector light studios, which can be used to project an image onto an object in the scene; and a Simple Sky folder.
The Templates archive contains all of the basic light shaders that are available. These can then be edited (as can all lights) to create the exact lighting you require (see Edit Lights for more information).
