Hello, I read this part of the manual: https://docs.unity3d.com/Manual/DrawCallBatching.html More precisely this part: "Built-in batching has several benefits compared to manually merging GameObjects together; most notably, GameObjects can still be culled individually. However, ut also has some downsides; static batching incurs memory and storage overhead, and dynamic batching incurs some CPU overhead." and now I am not sure, if the highlighted part is a typo or an acronym I don't know.
