Full lighting (Environment light plus environment IBL)—The material is affected by a combination of the light produced by the environment IBL and the environment light that illuminate one particular area of the surface.
Environment light only (if any)—The material is affected by environment lights that create highlights and other lighting effects on a specific region of the surface, but not by the IBL light from the environment. To add an environment light, select Scene > Light and Shadow.

Environment image-based lighting (IBL) only—The material is lit only by the IBL light in the environment and not by an environment light.
