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 pane, expand the Recommended archive, and choose the desired background effect.
3 Drag your chosen background into the palette on the right 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 Render 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 needed.
Each editor will be different for each type of background.
4 Click OK.
To add an environment background
1 Open the Presenter window, and click the Effects tab.
2 In the left pane, expand the Recommended archive, open the Environments subfolder, and then open the
Panorama folder.
3 Drag the Sky effect over to the palette on the right.
The background is not yet visible in the Scene View.
4 Return to the Recommended archive, open the Backgrounds subfolder, and drag the Environment effect
over to the palette.
The background is now visible. This is because this type of background is made up of two parts, the Sky
image and the background Environment shader that points at the image; the two elements link together
automatically.
Once this is complete, moving around the model will see the background moving appropriately in real-time.
With a modern graphics card, if there are reflective surfaces in the scene, setting the Presenter Hardware Shading
in the Options Editor to Lighting will show the newly set up background reflected in all such surfaces (see
“
Presenter Page” on page 472).
TIP Click Render to show this background in the photorealistic output.
