Creating a variant with script without instantiating it in the scene

Hi everybody!

I can currently create variants using the code suggested here:

[Solved] Creating Prefab Variant with script

Hello, I’ve looked into the PrefabUtility class, it doesn’t seem to provide any useful method to do so. I also tried by script to instantiate a variant prefab, modifying it and then making it a prefab again, it doesn’t keep the “base prefab” attribute in the inspector (it does if you do that in the editor and choose to create a ‘new original Prefab’ when making a prefab from the instantiated gameobject). Thanks Edit: Solved

Object originalPrefab = (GameObject)AssetDatabase.LoadAssetAtPath(prefabPath, typeof(GameObject));
GameObject objSource = PrefabUtility.InstantiatePrefab(originalPrefab) as GameObject;
GameObject prefabVariant = PrefabUtility.SaveAsPrefabAsset(objSource, localPath);

The problem is that it generates an instance of the original prefab in the scene and I would like to avoid that, since the components in the prefab execute some editor code on Awake and that should not happen.

Isn’t there any other method that just creates the variant asset without instantiating it?

Thanks in advance.

It’s impossible to do it. This thread can be closed.

A variant of a Prefab it’s just an instance of that Prefab - you need one to create a variant.
One option is to create the instance in a PreviewScene and save that instance as a Variant. This is how we do it internally to avoid affecting the current scene.

Hi Mirceal, thank you for your answer. It’s nice to know that technical solution for not affecting the scene, but there must be another thing you do that lets Unity avoid executing the Awake method of the new variant. If I right click on a prefab and create a variant using the context menu, Awake is not called.
