To use your backpacks, set the following bind to open the backpack using using B ingame.
This is due to recent Rust changes where the server can no longer set binds on your behalf. To set the proper bind, press F1 and type into console the below pressing enter after each one:
bind b backpack.open
And backpacks should open after pressing B! Please note that ‘writecfg’ is very important as it saves the binds so they come back after a Rust restart.
This will bring up an extra storage inventory as pictured above. Deposit items in this area as you please! Please keep in mind however that if you die, someone else can also Loot your backpack as they would your body. Players with Backpacks will look like the below:
