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 reflection is view-aligned. Mudbox aligns its SEMs to the light.
Lit Sphere is another name for SEM.
- ZBrush MatCap materials use SEM.
- Mudbox Lit Sphere material uses SEM.

- LitSpheres in Max viewport Polycount thread has Max & Maya FX shaders and many example Lit Spheres.
- Toon/Comic Shader for 3ds Max by Till "Rollin" Maginot supports LitSpheres. More info in the Polycount thread TF2 and TOON realtime viewport shader (3ds max).
- Mudbox Litspheres creation - by Pior "pior" Oberson, timelapse video of him creating Lit Spheres.
