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).
