Assign scenery
Create a Scene to give your model's rendered image an ideal look. A scene is a collection of rendering entities that define the rendering environment. It can contain a background, a foreground and an environment. It can also include scenery, such as a base on which the model rests, a panorama, or a room to house your model. The environments in the scenery are useful to fine tune the reflections of the model in Realtime rendering to emulate the true model reflections.
To apply backgrounds, foregrounds, environments, and other scenery to a scene,
1. Click the Scene tab in the Rendering Browser.
2. Right-click the scenery you wish to apply and select Apply to Current Scene, or drag the scenery and drop it in the viewport.
Newly assigned scenery replaces existing scenery of the same type. For example, anew background replaces a previously assigned background.

If you use a background image in your scene, the rendered image can be enhanced by adding shadows cast by your model on the background image. Do this by creating geometry that roughly resembles the portion of the background image that should receive the shadow, then assign the Shadow Catcher reflectance shader to this geometry.
Similarly, you can cast shadows on an imaginary floor using the Drop Shadow scenery.
