Untiy 打包LightMap 报错:Inconsistent asset when sorting preload assets: '' fileID: 0

[BigAzrael]

版本:Unity 2017.2.f1(64bit)

代码:

LightMaps lightMaps = ScriptableObject.CreateInstance<LightMaps>();
int count = LightmapSettings.lightmaps.Length;
lightMaps.lightmapColor = new Texture2D[count];
lightMaps.lightmapDir = new Texture2D[count];
lightMaps.shadowMask = new Texture2D[count];

for (int i = 0; i < count; i++) {
        lightMaps.lightmapColor[i] = LightmapSettings.lightmaps[i].lightmapColor;
        lightMaps.lightmapDir[i] = LightmapSettings.lightmaps[i].lightmapDir;
        lightMaps.shadowMask[i] = LightmapSettings.lightmaps[i].shadowMask;
}

AssetDatabase.CreateAsset(lightMaps,"Assets/RealV/LightmapTexture/LightMaps.asset");
SetAssetBundlesName(path);
BuildPipeline.BuildAssetBundles(targetSourceDir, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows);

报错:
Inconsistent asset when sorting preload assets: '' fileID: 0
UnityEditor.BuildPipeline:BuildAssetBundles(String, BuildAssetBundleOptions, BuildTarget)
com.RDTech.Tools.Unity.Editor.CreateObjectTree:rdBuild() (at Assets/Scripts/Editor/CreateObjectTree.cs:43)
