Environment backgrounds are images wrapped around the model. The recommended images to use are vertical
cross maps. These images are automatically placed on the inside of a cube that then surrounds the scene. Due
to the nature of the feature, edges and corners become indistinguishable. A wide variety of environment maps
are available for purchase on the internet.
Setting up an environment background consists of two components: the background image, such as the sky over
the desert, and the environment that holds the background image.
To add a background effect
1 Open the Presenter window, and click the Effects tab.
2 In the left-hand pane, expand the Recommended archive, and choose the desired background effect.
3 Drag your chosen background onto the palette on the right-hand side.
Most backgrounds can be rendered interactively in OpenGL so you have a good preview of how the
background will be fully rendered.
4 Click the Render button to apply the background to the model.
To edit a background effect
1 Open the Presenter window, and click the Effects tab.
2 Double-click the required background in the palette.
3 Use the Background Editor to adjust the settings as necessary.
Each editor will be different for each type of background. The Scaled Image editor is shown here.
