Move items between inventories

Looking for a tutorial that will show how to move inventory items between inventories.

Say I want to be able to push metal to the furnace to smelt to ingots.
Or pull them back out.

I know it can be done, and should be easy.

Just can’t find a tutorial to show me how to get started (or I don’t know what to look for).

I don’t have my devkit on this pc so I can’t give an exact answer, but I’m fairly certain you can grab a reference to the container’s inventory component and add / remove items through it. If you check the wyvern’s base bp, it shows in blueprint form how they add the milk when it’s knocked out.
