No
Default References of nested Serializable classes are not exposed in the Inspector
Reproduction steps:
1. Open the attached “IN-50785 Default References not exposed.zip“ project
2. Open the “SampleScene”
3. Select the “GameObject” in the Hierarchy
4. Notice that the “Mono (Script)” component in the Inspector has a Material reference from the “Nested” class
5. Select the “Mono” script in the Project window
6. Observe the Inspector
Expected result: The Material reference from the “Nested” class is exposed on the “Mono” script
Actual result: The Material reference from the “Nested” class is not exposed on the “Mono” script
Reproducible with: 2021.3.30f1, 2022.3.9f1, 2023.1.12f1, 2023.2.0b8, 2023.3.0a4
Reproduced on: Windows 11 Pro (22H2)
Not reproduced on: No other environment tested
Notes:
- Reproducible in a new project
- Adding “MonoBehaviour” inheritance to the “Nested” class exposes the Material reference on the “Nested” script but then on the “Mono” script and the “GameObject” it appears as “None (Nested)” and nothing can be referenced through it

- Volumetric fog shader variants are missing from build when "Strict Shader Variant Matching" is disabled
- Unnecessary modifications clutter the Scene when using a RectTransform driven by a LayoutGroup in a Prefab
Resolution Note:
This is by design, only objects that inherrits from UnityEngine.Object is allowed as defaults.
The closes solution to what want is to make the Nested object inherrit from ScriptableObject and then create an instance of it (using CreateAssetMenu attribute and make an instace under Create -> Nested) and assign that instance as the Default reference to the Mono script
[CreateAssetMenu]
public class Nested : ScriptableObject
{
public Material _Material;
}
