EDIT: or maybe... What if I did this: since my backpack will be fullscreen I need to raise the distance to target of my camera to a high amount.
Then I'll create destructables for a background etc.
Then I'll create the trackables on top of a very high invisible platform.
Then once the player is done doing whatever he wants in his fullscreen inventory, he/she closes the inventory
(the trackables will still exist but in such a high z height that they can not be hovered or clicked on through the normal game camera).
But then again, if a player goes to the exact same spot with his/her camera as he/she did before and the trackables are still there... It might bug.
I really need some advice on this from some people with more knowledge on this subject
