Module generate 

Like EnvironmentMapLight, but filtered in realtime from a cubemap.

An environment map needs to be processed to be able to support uses beyond a simple skybox, such as reflections, and ambient light contribution. This process is called filtering, and can either be done ahead of time (prefiltering), or in realtime, although at a reduced quality. Prefiltering is preferred, but not always possible: sometimes you only gain access to an environment map at runtime, for whatever reason. Typically this is from realtime reflection probes, but can also be from other sources.

In any case, Bevy supports both modes of filtering. This module provides realtime filtering via bevy_light::GeneratedEnvironmentMapLight. For prefiltered environment maps, see bevy_light::EnvironmentMapLight. These components are intended to be added to a camera.
