Environments are HDR (High Dynamic Range) images that can be applied to any rendered scene. Setting an environment enables IBL (Image-Based Lighting) in your scene. This lights the scene using the sun and sky in the environment image you choose, providing dramatic reflections and shadows.
The following environment images are available from Autodesk® Rendering. Although they look distorted here, they appear correctly when mapped to your camera views.

Riverbank
Crossroads
