Set a Custom Background Environment Map

To create a more nuanced rendering environment, you can set a Custom Background Map.

1. On the ribbon, click the Rendering tab.
2. Click the Environment icon.
   
   
3. In the Control Panel, enable Custom background map, and define the following:

   Option	Description	Note
   Wrapping	Define how the image is projected around the objects in your scene: Spherical: Use for rectangular images. Projects the image around your scene in the shape of a sphere. Hemispherical: Use for rectangular images. Projects the image around the upper half of the sphere. This is useful for depicting objects on a ground plane, so that reflections do not show underneath. Angular Probe: Use for images taken with a fisheye lens.
   Rotation	Rotate the map. This will affect how the scene is illuminated.
   Intensity	Define the brightness of the map. Type a value from 0 to 1, where the default value of 1 corresponds to 100% intensity. Lower values darken the scene, while higher values brighten the scene.	Decrease the intensity if you plan on adding lights or emitters to your scene.
   Horizontal offset %	Zoom in on a specific area of the background map by shifting 0–50% of the image in the horizontal direction. To move 0–50% of the image to the right, enter a Offset Horz value between 0 and 50. To move 0–50% of the image to the left, enter a Offset Horz value between 0 and -50.	Only available for Background Map.
   Vertical Offset %	Zoom in on a specific area of the background map by shifting 0–50% of the image in the vertical direction. To move 0–50% of the image upward, enter an Offset Vert value between 0 and 50. To move 0–50% of the image downward, enter an Offset Vert value between 0 and -50.	Only available for Background Map.
   Scale	To resize the background map, enter a scale factor.	Only available for Background Map.

4. Right-click and mouse through the check mark to exit, or double-right-click.
