Save mesh as prefab with Mesh Renderer material

Hi everyone,
can I save a mesh as a prefab keeping the material information?
With this code I save the mesh as mesh.asset and as mesh.prefab but the material is lost.

Code (CSharp):

1. GameObject newMesh = GameObject.Find("mymesh");
2. Mesh msh = newMesh.GetComponent<MeshFilter>().sharedMesh;
3. AssetDatabase.CreateAsset(msh, assetpath);
4. PrefabUtility.SaveAsPrefabAsset(newMesh, prefabpath);
5. AssetDatabase.SaveAssets();
6. AssetDatabase.Refresh();

Is there any way to keep this information?
Would it be possible to add the material to the prefab without it being present in the Hierarchy (directly on the prefab on the disk)? I looked at the Unity documentation and it would seem possible to add components but I did not find anything about the material.

 

I take it the Material is not already saved as an asset?

You should be able to use https://docs.unity3d.com/ScriptReference/AssetDatabase.AddObjectToAsset.html to add it to the Prefab Asset.

 

Thanks for your answer.
I try your suggestion.

 

I'm afraid I'm only halfway, I find these steps a bit difficult.
I followed your instructions but I only managed to add the material as "sub-object" to the prefab.
Materials in Mesh Renderer is always empty, you need to drag it into the field.

Code (CSharp):

1. GameObject newMesh = GameObject.Find("mymesh");
2. Mesh msh = newMesh.GetComponent<MeshFilter>().sharedMesh;
3. AssetDatabase.CreateAsset(msh, assetpath);
4. PrefabUtility.SaveAsPrefabAsset(newMesh, prefabpath);
5. Material material = new Material(Shader.Find("Standard"));
6. AssetDatabase.AddObjectToAsset(material, prefabpath);

Also I read that it is necessary to re-import the prefab for the changes to be visible without having to save the project.
Unlike the example, however, I do not create the asset but I use an object in the Hierarchy.

So I tried to reload it but it's not the right way.

Code (CSharp):

1. Object newObj = (Object) AssetDatabase.LoadAssetAtPath(prefabpath, typeof(Object));
2. AssetDatabase.ImportAsset(AssetDatabase.GetAssetPath(newObj));

Could someone tell me the steps to save a mesh as a prefab with all its components or add them later?
I'm looking for two days in the forums, so it's impossible?
Thanks

 

Hi all
The solution can be found in the sample located at
https://docs.unity3d.com/ScriptReference/PrefabUtility.html

The key is to use
Object prefab = PrefabUtility.CreatePrefab(localPath, obj);
PrefabUtility.ReplacePrefab(obj, prefab, ReplacePrefabOptions.ConnectToPrefab);
