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