7.6 Light settings

This dialog box that can be opened selecting View -> Light in the main menu, allows the light source management.

Lighting

The VEGA ZZ light engine supports up to four directional light sources plus the ambient light. The number of the directional light could be reduced to one if the graphic card OpenGL driver doesn't support more than one light source. Each light source, selectable with the Sources box, can be independently enabled or disabled (see Enabled checkmark in the Position box) and moved in the scene clicking the small buttons in the corners of the blue box. To move inside the blue box position layers, you must click on the layer outside the small buttons and to show all layers, you must click the button. For each light source, can be changed the diffusion and the specularity colors in the Light colors box. The ambient light can be switched on or off and it's possible to change its color (see Ambient light box).
In Lighting window, it's also possible to change the Material properties as the specularity (from 0 to 100), the shininess (from 0 to 100) and the vector reflection (enabled/disabled).
To revert to pre-defined lighting parameters, you can click the Default button.
The lighting engine could be disabled unchecking the Lighting enabled item at top-left window position.
