To copy lighting effects into a custom folder
1 In the Presenter window, Lighting tab, click a lighting effect in the right pane, and drag it to the desired
location under the My Lighting folder in the left pane until a mouse pointer displays a small plus symbol.
2 Release the left mouse button to drop the lighting effect into the folder.
NOTE You can also copy lighting effects between the folders in the left pane by either dragging and dropping
them, or using the Copy and Paste options on the shortcut menu.
To manage palette lights
➤ Right-click a light in the right pane of the Lighting tab (the palette).
■ Click Copy to copy the light to the clipboard. Right-click an empty space in the palette and click Paste
to paste a copy of the light with the same name suffixed with the next number in the list.
■ Click Delete to delete the light from the palette. This will also remove the light from the scene.
■ Click Rename to rename the light. You can also select the light and press F2 to rename it.
■ Click Edit or double-click a light to open the Light Editor dialog box, allowing you to edit its parameters.
See “
Edit Lights” on page 363 for more information.
■ Click Clear Palette to delete all the lights from the palette and hence from the scene.
Edit Lights
You can edit a light in the palette by double-clicking it, or right-clicking and choosing Edit on the shortcut menu.
There are six types of light visible in both OpenGL interactive renders and photorealistic renders:
■ Ambient lights give a general background light to the scene and therefore only have Intensity and Color
parameters.
■ Distant lights are directional and so have a location and target. However, the location and target merely set
up an axis down which the light shines, as these light types are infinitely far away and their beams are parallel.
As well as Intensity and Color parameters, they can also cast shadows in a photorealistic render.
■ Eye lights are located at the viewpoint and also only have Intensity and Color parameters.
■ Point lights have a location but shine in all directions. They also have an Intensity and Color and additionally
can cast Shadows (only available in a full photorealistic render).
■ Spot lights are also directional and therefore have a location and target, as well as Intensity and Color, and
shadow parameters. In addition, they also have parameters for affecting the light’s Fall Off and Cone Angle,
as these light types are not infinitely far away, so do spread their light over a cone and the intensity does
diminish away from the light.
