NOTE If the Presenter profile in the Options Editor (see “Presenter Page” on page 405 for more information) is set to
Advanced, the dialog box will include the full list of parameters and allow you to change the type of background.
In the Background Editor, click the Browse button (...) next to the File Name field to display the Open Image
File dialog box. From here, browse to an image file and click Open to use that image as the background.
Editing parameters in the Background Editor will interactively alter the scene with those changes.
At any time, click the Apply button to apply the parameter edits to the scene.
You can save an edited background for use in other scenes by simply dragging it into the Backgrounds folder
inside the My Effects user archive.
Environment Background and Reflections
Environment backgrounds are a special kind of background that move with the model and allow reflections
from reflective model parts.
Environment backgrounds not only make the scene look more realistic for static images of the model, but
completely transform the realism effect in animations. This is because as in real life, by moving an object around
in the background, the environment also changes. For example, looking up to the top of a building, the
background will be the sky, whereas, an aerial view of the building will have the surrounding buildings or
landscape as the background.
Another benefit of using environment backgrounds is that reflection properties of materials in the model are
able to reflect the environment (for example, when looking up, towards the top of a glass-fronted building, the
sky is reflected in the glass.
