FindRelativeProperty custom class

SerializableProperty's FindRelativeProperty is working fine for one property in my script that is a MonoScript but my custom class (which is a public property in the same object) isn't being picked up by it. Is there a requirement for the function to be able to pick up these properties? The custom class is Serializable and if I change it to inherit from anything, none of the properties are available to FindRelativeProperty.

Thanks!

 

It seems that if you're trying to find a field of an object that is the same type as that object, it doesn't like that. I separated that piece of functionality out to another custom class and it works now.
