In unity does Lightmapping require that 2 duplicate objects e.g two exact same tables in the same scene have separately laid out UV / texture maps? or can the initial UV’s share the same texture file and space.
Lightmapping requires unique UVs for everything. However if you use the built-in lightmapping you don’t have to worry about it, it’s all automatic. Also the lightmap uses the second UV set, so the primary UV set isn’t touched.

Good to know thanks,I’ve brought Maya baked lightmaps into Unity but its a slow process.Wasn’t sure if Unity would need new maps for everything,I presume you would just need basic/clean maps for every object since it creates its own secondary set.
