In Sons of the
To build tent in Sons Of The Forest, you need two materials: a tarp and a stick. You can collect a tarp at the beginning of the crash site and sticks can be found everywhere. You can also ask your companion Kelvin to find a stick for you.
If you have the required materials, you can open your inventory and get the tarp.
Then spread the tarp out on the ground where you want to set up your tent.
Then go to a corner of the tarp and a dashed arrow will appear pointing up.
Interact with it with the left mouse button (or RT/R2 on the controller) and your character will automatically place a stick if you have one in inventory.
