Hello,
I read this part of the manual:
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.
