UEFN Fortnite Loot Pools: Spawn Default Chest, Ammo Box and Supply Drop Loot

UEFN Fortnite loot pools give Verse creators six ready-made reward categories in Fortnite 43.10: regular and rare chests, regular and rare ammo boxes, supply drops and food boxes. They belong to the experimental Loot Pool API, which means islands using them cannot be published yet.

The built-in pools are useful when you want familiar Fortnite-style rewards alongside a custom table. You might use a normal chest selection for everyday loot and a separate weighted pool for a special island reward. Epic says these pools can be combined, but the API is still experimental and islands using it cannot be published.

The six built-in UEFN Fortnite loot pools

The documented pool types are fort_loot_pool_chest for ordinary chests, fort_loot_pool_chest_rare for rare chests, fort_loot_pool_ammo_box for ammo boxes, fort_loot_pool_ammo_box_rare for rare ammo boxes, fort_loot_pool_supply_drop for supply drops and fort_loot_pool_food_box for food boxes.

The names describe the source of the loot category. They are not weapon IDs, item-granter device names or a list of every possible item that could be selected.

When to use built-in UEFN Fortnite loot pools

Use the built-in pools when you want familiar Fortnite-style loot without defining every possible reward. Build a custom weighted pool when a chest needs exact categories or rarities, or a nested pool when it should choose from several reward groups. The new Loot Pool API still needs a lootable object and a way to deliver the selected items.

Do UEFN Fortnite loot pools match the live Battle Royale season?

Epic says these pools can roll the same loot Fortnite uses, but the release notes don’t provide a fixed item-by-item table for each category. If your island needs a specific reward, check what the experimental pool returns in the current build. Don’t treat a Battle Royale loot chart as a guaranteed list for your custom chest.

UEFN Fortnite loot pools: how to compare default and custom rewards

In an unpublished test, keep the loot source simple. Select a documented built-in pool and record the result over multiple accesses. Test one container category at a time so you can see what changes when you switch from a chest to an ammo box.

Then compare that behaviour with a tiny custom weighted table using fixed entries. This is much easier to debug than combining default loot, nested bonus pools and player-specific conditions on the first pass.

What causes missing or unexpected rewards

First establish whether the lootable object actually requested a selection. Then confirm the pool type matches the container you intended. If loot was selected but not granted, the issue may be in the part of your project that awards or spawns it.

If an item differs from your expectation, check whether you assumed a live Battle Royale pool that Epic did not promise would stay identical. Avoid inventing item IDs or a compile-ready class constructor just to fill a guide.

Where to find UEFN Fortnite loot pools in Verse

The six built-in UEFN Fortnite loot pools belong to the Fortnite.com LootPools module. Epic’s custom weighted and nested pool types are documented under UnrealEngine.com LootPools. That distinction matters if you’re looking at API references and can’t find a class where you expected it. Check the module path shown on the current reference page before writing an import statement.

Start by testing one built-in pool, such as a regular chest, and log the returned selection. Then try a rare chest or ammo box as a separate test. Keep the lootable entity and reward-delivery logic the same so you can compare the pools themselves. The API is experimental, so run these tests in an unpublished project.

UEFN Fortnite loot pools FAQ

Does a built-in chest pool match a particular Battle Royale season? Epic does not promise an exact season snapshot for every creator island.

Can I combine a built-in pool with custom rewards? Epic says custom and Fortnite pool selections can be mixed, but test the resulting rolls.

Can these pools be used in published islands? Not in 43.10, because the Loot Pool API is experimental.
