Unity clone 场景渲染的灯光贴图异位问题

问题

需要将一个场景clone 一份保存到本地
当克隆完成后，副本场景的灯光贴图异位了，与原场景存在较大的差别

问题原因

场景被clone 后，场景的灯光渲染数据不能共用，即Lightmapping.lightingSettings 两场景可以公用，但 Lightmapping.lightingDataAsset 数据不能共用。

解决办法

场景被clone 后，重新调用unity 的Bake方法，对新场景重新灯光烘焙。
附上相关代码：

        EditorSceneManager.SaveScene(scene, newPath, false);//bake new copy scene,  when clone a scene, the reference of the light data will be broken.if (Lightmapping.lightingSettings != null && Lightmapping.lightingDataAsset != null){//EditorSceneManager.OpenScene(scene.path, OpenSceneMode.Single);var sourceLightingSettingPath = AssetDatabase.GetAssetPath(Lightmapping.lightingSettings);var newLightingsettingPath = Path.Combine(Path.GetDirectoryName(newPath), Path.GetFileNameWithoutExtension(newPath) + ".lighting");File.Copy(sourceLightingSettingPath, newLightingsettingPath, true);AssetDatabase.ImportAsset(newLightingsettingPath);var lightingSetting = AssetDatabase.LoadAssetAtPath<LightingSettings>(newLightingsettingPath);EditorSceneManager.OpenScene(newPath, OpenSceneMode.Single);Lightmapping.lightingSettings = lightingSetting;Lightmapping.lightingSettings.autoGenerate = false;Lightmapping.Bake();EditorSceneManager.SaveScene(EditorSceneManager.GetActiveScene(), newPath);}```
