ScriptableObject serialization in prefabs

Hi guys

I've hit a very worrying problem with ScriptableObject, and I'm not sure what the correct way to proceed is.


For a little backstory, there is a known bug with ScriptableObject and the use of SerializedObject.FindPropertyRelative: it always returns null.

http://answers.unity3d.com/questions/543010/odd-behavior-of-findpropertyrelative.html

I have made and submitted bug reports, but I haven't heard anything in months.


I have an object hierarchy that looks like this:

HydraParticleEmitter (MonoBehaviour)
---> EmissionShape (ScriptableObject)
-------> Child data (ints, floats, you name it)


In a perfect world I would be able to use FindPropertyRelative when drawing my custom inspector for the grandchild properties. Because of the aforementioned bug this is impossible.

My workaround for this has been to do the following:

Code (CSharp):

1. private void DrawShapeContent()
2. {
3.     // Note I am having to create a new SerializedObject to get access to the children
4.     SerializedObject emissionShape = new SerializedObject(m_EmissionShapeProp.objectReferenceValue);
5.     EmissionShapeInspector.DrawInspector(emissionShape);
6. }

This works great for instances (despite not working with multi-object-editing):




However, it fails miserably when drawing the inspector for a prefab:



The error comes from the line:

Code (CSharp):

1. SerializedObject emissionShape = new SerializedObject(m_EmissionShapeProp.objectReferenceValue);

It turns out that m_EmissionShapeProp.objectReferenceValue is returning null when drawing the inspector for a prefab.


My questions are:

• SerializedProperty and ScriptableObject have been broken for a long time, and I'm really not finding many google results for these problems. This suggests that my workflow is way off the beaten path. Can anyone advise on how I can correct my object hierarchies so they will work correctly with Unity's serialization?

• Why does SerializedProperty.objectReferenceValue return null when the parent is a prefab?

Thank you for any advice you may have. I sympathise with anyone who has battled with Unity Serialization in the past.

Dont know the answer, but saw this few days ago, maybe it helps?
