Unity clone 場景渲染的燈光貼圖異位問題

問題

需要將一個場景clone 一份保存到本地
當克隆完成后，副本場景的燈光貼圖異位了，與原場景存在較大的差別

問題原因

場景被clone 后，場景的燈光渲染數據不能共用，即Lightmapping.lightingSettings 兩場景可以公用，但 Lightmapping.lightingDataAsset 數據不能共用。

解決辦法

場景被clone 后，重新調用unity 的Bake方法，對新場景重新燈光烘焙。
附上相關代碼：

        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);}```
