Adding lights

Adding Lights to Your Model

Use the following procedure to add an artificial light to your drawing:

Draw and position the object which will serve as your light source. Once this object is tagged as a light source, it will emit light in the pattern you choose.
Use the New Light dropdown button on nXt's Lighting tab to select a pattern for your light. Four patterns are available:

//Omnidirectional// distributes light in all directions equally.
The //Spot// pattern provides a beam which you can focus.
//Diffuse// provides an approximation of a recessed light with a diffuser or baffles.
The //Photometric// pattern allows you to use a manufacturer's .ies goniometry file to describe the distribution.

When prompted select your object (the Photometric pattern will first prompt you for your .ies file.)
Provide a name for your light.
Hit enter to accept default values for the other prompts.

By default, all lights will direct their light straight down. Depending on your scene, you may need to aim your light in a different direction. Before you begin the aiming process, it is often easier to have a target object to snap to. Right click on the light in the list, and select Aim < to aim your light. The different patterns will have different prompts to follow.
To change the properties of your light, right click on the light in the list and select Properties.
