Unlike our official DLC, Creator DLC data are not present in a regular Arma 3 installation. This is to avoid regular Arma 3 installations requiring a lot more additional storage for those who do not own and have no interest in particular Creator DLC. The second reason is that a Creator DLC's theme or setting might be very different from regular Arma 3, and not everyone will want the content to be visible in their game.

To ensure multiplayer compatibility between owners and non-owners of Creator DLC, a compatibility data pack has been introduced. It is a Steam Workshop item which contains full Creator DLC data. Upon subscription, Creator DLC data will be added to user's base Arma 3 installation.
