Hello Aftersun,
In the demo examples there is no player looting but there are plenty of ways you can have the player character become loot-able on death.
One way you could easily do it, is to move the Equipment Inventory Component to the Player Character instead of having it in the Player Controller (but keep the Inventory Manager Component on the Player Controller) and have it so the players body can be used by players when dead like any other usable container item. This would allow you to view it like a container and interact with it’s items. You can easily create a new Loot UI specifically for players to display where the items are equipped and when you loot an equipped item have it update the corpse to remove the mesh showing you took that players jacket, helmet, weapon, etc…
After taking a bit of time to understand the system it should be very straight forward to customize it and add additional features for your own projects specific needs without too much work.
There are no container in container examples in the demo content and that would take a little bit more work to build depending on how you want it to work.
You could create a new item type that’s a container and make it so that the item has a reference to it’s own inventory and when used in the inventory it opens a container window.
