Question by gabriele_unity931 · Sep 19, 2019 at 09:57 PM · materialassetbundlefile

How do I save a material from an asset bundle to file locally ?

My goal is to save to file the material contained within the AssetBundle in Editor Mode. Given the function below I keep getting the error:


"Couldn'd add object to asset file because the Material 'my_material' is already an asset at '' !"


It's kind of confusing because the Material m that is coming from the LoadAsset method is nowhere to bw found in the "Assets" folder and the "Assets/materials" one is empty.


 public static Material SaveMaterialToFile(bute[] assetData, string materialName) {
   AssetBundle b;
   Material m;
   
   AssetBundle.UnloadAllAssetBundles(true);
   b = AssetBundle.LoadFromMemory(assetData);
   m = bundle.LoadAsset<Material>(materialName + ".mat");
 
   b.Unload(false);
   AssetDatabase.CreateAsset(m, "Assets/materials/" + maeterialName + ".mat");
 
   return m;
 }


At this point I am not sure how to proceed. I tried multiple things and although it seems straightforward, I can't get it to work. Any suggestion ?
