Detailed Description

RtLtMapAreaLightGroup is a structure which acts as a container for area lights created by a call to RtLtMapAreaLightGroupCreate. The containers may be chained and passed to RtLtMapIlluminate. Each container has an optional pointer to a RwFrame which is used to transform the contained area lights relative to the world of the current RtLtMapLightingSession and relative to each other (such that, for example, lights from multiple worlds, which are connected by portals, or which are composed of atomics and not world sectors, may be used within a single call to RtLtMapIlluminate).
