Unity has also provided a clear link to academic standards for science, technology, engineering, art and math (STEAM) by providing a crosswalk between these professional skills and academic standards like the Common Core. In this version, Directional Lightmaps and the Forward Rendering path are not supported. Unity sometimes replaces those upon import with some other symbols and may therefore break your postprocessor scripts when they will look for the lightmap textures. For designs that do not adhere to any of the rules-of-thumb for contiguous UVs, like ones that have a lot of geometry or negative space with few elements, you will need to split the UV charts and add much more padding to prevent artifacts.
