To use the Restrained Love features built in to Firestorm you need to follow a few simple steps:
Firestorm Quick RLVa Setup - Preferences
Press CTRL-P to open the Preferences panel.
Go to Firestorm
Move on to General
Check on "Allow Remote Scripted Viewer Controls (RLVa)"
After this you have to restart Firestorm to get RLVa working. Additionally you usually need to get a so-called Relay. This is an attachment you wear that enables objects in-world to interact with your viewer. These Relays are usually free of charge and come as HUDs or pieces of jewelry you wear. It's recommended to get a "Multi Relay", so you can be controlled by more than one device at the same time.
If you also want to enable traps and toys to put folders into your inventory, you need go through a few additional steps:
For Firestorm v4.2.2 and earlier: Press CTRL-P to open your Preferences panel, then go to Privacy. Find the option "Automatically accept inventory items" and disable it.
Click on the RLVa menu
UncheckForbid Give to #RLV
Open your Inventory (CTRL-I)
Right click on My Inventory
Select New Folder
Rename the new folder to #RLV (be sure to use uppercase letters, exactly as shown here)
Firestorm Quick RLVa Setup - Uncheck "Forbid Give to #RLV"
Firestorm Quick RLVa Setup - Create a new Folder - Step 1
Firestorm Quick RLVa Setup - Create a new Folder - Step 2
Firestorm Quick RLVa Setup - Create a new Folder - Step 3"
Now you should be able to accept inventory from traps and toys, which will automatically be moved into the #RLV folder tree.
