### Remarks

Unity invokes the `OnAfterDeserialize` callback on an object after deserializing it. In this callback, you can transform the deserialized data back into your preferred runtime data type.

Refer to [Custom serialization](/engine/6000.6/manual/scripting/compilation-and-code-reload/script-serialization/custom-serialization.md) in the Manual for more information.
