Use editor

Go to the editor and then place a playable unit. Once you have placed a playable unit you want to go to the "Empty" tab in the editor and then select the Australian Buildings. Then once you select them you can place any item in the pack that you want. Just so you know, if you place the bank and run inside it, you will hit invisible walls and in order to see that walls you must place them from the Australian Map Objects tab.

Some ways you can use the mod:

Use it along side X-CAM and Terrain Builder to create your own map (there are loads of tutorials for this out on how to do this).

If you don't like that then you can use the mod with Zeus and MCC 4 (Mission Control Center Sandbox 4) to make a mission

If you don't want to make a terrain mission but edit an existing map with out making people be force to install a terrain then you can use the normal arma 3 2D editor and remove buildings (codes can be found on the arma 3 forms and wiki) and place your buildings over the top.


Hope this helps!
