 # Objective Lightmaps, textures that store baked global illumination, have been a mainstay of real-time graphics for decades. Bevy currently has no support for them, so this pull request implements them. ## Solution The new `Lightmap` component can be attached to any entity that contains a `Handle<Mesh>` and a `StandardMaterial`. When present, it will be applied in the PBR shader. Because multiple lightmaps are frequently packed into atlases, each lightmap may have its own UV boundaries within its texture. An `exposure` field is also provided, to control the brightness of the lightmap. Note that this PR doesn't provide any way to bake the lightmaps. That can be done with [The Lightmapper] or another solution, such as Unity's Bakery. --- ## Changelog ### Added * A new component, `Lightmap`, is available, for baked global illumination. If your mesh has a second UV channel (UV1), and you attach this component to the entity with that mesh, Bevy will apply the texture referenced in the lightmap.
