It is important to be able to view the lightmap UVs that are being used, and Unity has a visualization tool to help you with this. First, open the Lighting window (menu: Window > Rendering > Lighting) and tick the Auto checkbox at the bottom. This ensures that your bake and precompute are up-to-date, and outputs the data that is needed to view the UVs. Wait for the process to finish (this can take some time for large or complex Scenes).

可以将多个实例打包到实时光照贴图中,因此您看到的某些图表可能实际上属于其他游戏对象。
To see the UVs for the Baked Global Illumination system:
如您所见,烘焙 UV 与预计算实时 UV 大不相同。这是因为烘焙和预计算实时 UV 的要求不同。
