Production and construction always require certain items.

To find exactly those items and resources that you need now, use Track function.

To track specific resources, select the resource in the production or construction menu and click "Track".

A number will appear next to the places on the map where the tracked types of resources are currently available for collection.

Place waypoint and go for the loot.

Remember that next time this resource may not be in the same place. The chances of resources appearing in different parts of the game world vary.

A list of all tracked items in the search can be opened in the map view by clicking on the Track List.

As long as you have tracked resources, the map will display a number next to the potential location of the item you are looking for.

A quick way to get the resources you need is to purchase resource packs from the in-game store.
