Question
`I get a null instance when trying to call a func from other tree how do I call that func if they are not in the same tree? or …scene? they are both there in the same main game. I have no clue what I’m meant to do to get around this even >_<

loot keeper is a control node with the item list as a child.
your pocket sand scene doesn’t have a child named “ItemList”, as you described “LOOTKEEPER” has the child you are looking for. How do you intend to get that node from this pocket sand scene?
bru thats what I want to know
