Is it possible to assign a new Instance ID to a prefab instance?

I'm doing some prefabs pooling and my code does some logic with the instances ID's.

But that causes conflicts when pooled instances get accessed when they shouldn't.

Is there some way to re-assign a new instance ID to a prefab instance, without instantiating & destroying?

Should be able to do it in debug mode (inspector top right) - wouldn't recommend dealing with instance ID though (unless you know exactly what you're doing) - how about you give your objects a script with an id that gets serialized and assigned once? then you can easily set/get the id then. EDIT: I'm not sure if you can set the instance ID at runtime though, debug mode is editor only

If you want to change the instance ID at runtime, you have to use reflection. There's an internal ReferenceData object in any UnityEngine.Object that has an int "instanceID" and an IntPtr "cachedPtr" - When you call GetInstanceID, it just returns m_UnityRuntimeReferenceData.instanceID` - so with little reflection you could set that instanceID easily
