Spherical Environment Map

Spherical Environment Mapping (SEM) is one of the simplest reflection mapping techniques.

When the camera moves around the object, the reflection is not very realistic since the same image is always reflected.

The image is usually aligned with the camera, although you could align it to other directions. For example Mudbox aligns its SEMs to the light, or in Unreal you can align SEMs to the Up vector (world space) and other directions.

Also called MatCap or Lit Sphere.
