How to modify the number of items overlapped and how to activate it correctly？
Hello!
Do you mean the item stack size? Like berries limited to 10 items per slot or copper ore limited to 250 items per slot?
yes!

This will require making a server mod. We don't yet have a modding guide yet, unfortunately, so you will need to figure out how to create a mod by looking at how other mods are made and figuring this out.
Basically, you will need to override this file and change its values:
QuoteCore.cpk\Scripts\Items\Base\ItemStackSize.cs
Then install this mod on the server.
However, please note that in order to properly work, the game clients will also need to use the same mod otherwise their stack sizes (when they split and combine items) will be still limited to the current stack sizes.
In the future, we're preparing to provide support for Steam Workshop so such mods will be automatically installed when connecting to the game server.
Regards!
