Perhaps I am missing something obvious, but I since updating to unity 5, it seems I am unable to bake only lightprobes, or even to bake lightmaps for only specific objects. Is there any reason that these options were removed? Or is there a way to work around this?
You can simply convert objects you dont want to lightmap into a perfab and copy the transform settings. Then you can delete those objects from scene. Then bake and place the prefab in the scene. Hope this helps
