根因分析
ScriptableObject 或 MonoBehaviour 具有深度嵌套的引用链(超过 7 层),超出 Unity 的默认序列化深度。
English
A ScriptableObject or MonoBehaviour has a deeply nested reference chain (more than 7 levels) that exceeds Unity's default serialization depth.
官方文档

-
Restructure your data to avoid deep nesting: flatten references by using IDs or asset references instead of direct object references. Example: replace `public List<ChildData> children;` with `public List<string> childGuids;` and load via Resources.Load.
-
Increase the serialization depth limit in Edit > Project Settings > Editor > Serialization Depth Limit to a higher value (e.g., 10 or 15).
-
Use `[System.NonSerialized]` on intermediate fields that don't need to persist, breaking the serialization chain.
无效尝试
常见但无效的做法:
-
30% 失败
Simply increasing the depth limit in Project Settings can mask the issue and lead to performance degradation from deep serialization.
-
50% 失败
Adding [SerializeReference] to fields does not reduce the depth; it only changes how references are stored.
-
70% 失败
Removing all nested objects breaks the data structure and loses functionality.
