Lightmap UVs and packing
Learn how Unity generates and packs lightmap UVs to store illumination for static geometry.

Lightmaps are pre-calculated lighting textures that store illumination for static geometry. Unity generates them via a multi-step process that transforms 3D mesh data into optimized 2D textures. Both the Realtime Global Illumination system and the Baked Global Illumination system use lightmaps, and therefore need lightmap UVs.
