I wanted to make a ring that greatly boosted your strength (just so I can transfer items and such more conveniently). I made the ring in the construction set, now how do I set the ring to appear in my character's inventory?

EDIT: Oops, this was suppose to go to the TES construction set board. I'll report this.

You want to drag it into the game world (render window) somewhere your character will be able to pick it up.

Can't I just make it automatically appear in my character's inventory, so all my character can start with it?

Maybe. Don't know if this would work, but in the NPC tab in the object window, find "player", double click it, then drag the ring into his inventory (items tab).

That worked! Only if you start a new character though, otherwise, I'll have to get the ring via console command for my other characters. No biggie though. Cheers!

You could add it to the player via a startup script. If you want to see an example, I recall abot's Water Life mod gives you some items. The basic idea is that the startup script runs, checks to see if it should add the item to the player (waits for after chargen and maybe other conditions), and then just does a player->additem

open the console,
Player->additem "insert the item ID here" 1
