Tutorial: Changing Scene Brightness
This tutorial will help you understand how the lighting controls work: follow these steps.
1 Open or create an Atmosphere environment.
2 Select View > Player View (F4) to open a Player view window.
3 Select the Window > Lighting Control menu command to open the Lighting Control palette. In the Settings tab
of the Lighting Control palette, enable all the light sources that you wish and set the Lighting Threshold to 25.
This will compute a fairly accurate lighting solution without updating the Player view. In the Quality tab of the
Lighting Control palette, select the Draft presets.
4 In the Controls tab of the Lighting Control palette, click on the Start button to begin the lighting solution. The
progress bars will move from right to left as the solution is calculated. Since the Lighting Threshold was set to 25,
the calculations will quit when the Light Remaining progress bar reaches 25.
5 As lighting progresses or once the lighting is fi nished, drag the Scene Brightness slider under the blue arrow at the
bottom of the Control tab in the Lighting Control palette. This will change the overall scene brightness..
