41.00 Fortnite Ecosystem Updates and Release Notes

Fortnite Ecosystem v41.00 brings Sidekicks to UEFN as NPCs, expanding the types of creature-based games you can build—including monster battlers, cozy farming games, creature-collection RPGs, companion adventures, and more. 

This release also introduces Custom Weapon Templates so you can reshape how Pistols, SMGs, Assault Rifles, and Shotguns look, sound, and play. Plus, expanded mobile development options with new touch controls and gesture support (experimental).

Additional updates include Skeletal Animation with Scene Graph (experimental), Live events support in Communities, more Star Wars™ characters added to the Hero device, new stability and asset management tooling, and more.

Sidekicks Now Available as NPCs for Your Islands

Fortnite Sidekicks are now available as scriptable NPCs in Unreal Editor for Fortnite (UEFN). Starting July 23, you can publish islands using Sidekicks as NPCs. You can customize how Sidekicks look, script their behavior with Verse, and animate them. You can even bring a player's own Sidekick into your game, putting the companion they already know at the heart of your experience. 

Get started with the following guides:

• Using Sidekick NPCs

• Creating a Sidekick

When publishing open, we will feature creature-based islands in a new creature-based Collection page, and they will also be eligible for additional Discover featuring opportunities, via Epic’s Picks, and a Callout. For details on the Creature Callout and how to submit, visit the forums. Head over to our blog to get all the details.

Compatible Weapons

Only certain weapons can cause damage to your Sidekicks. For a complete list of weapons that apply damage to them, see Damaging Your Sidekick. 

Cozy Architecture Kit, Pet Props, Foliage, and Farming Items Added

With Sidekicks coming to UEFN, we have added new galleries you can use to build your ultimate Sidekick experience.

• Plumpton Architecture Kit and Prefabs: A quaint country life architecture kit and prefabs

• Plumpton Farm Gallery: Crops and soil patches with multiple states to suit farming type games

• Pet Props Gallery: Treats, toys, grooming gear, and accessories

• Updated Foliage: New and improved grass and flower options for landscapes

Plumpton Feature Example

Get started with the Plumpton feature example for UEFN, a cozy town perfect for creature companions. This project includes Sidekick NPCs, a farmhouse, crop fields, training grounds, and more.

The template is available in the Project Browser, under Feature Examples > Game Examples > Plumpton: Environment.

Hero Device Update – New STAR WARS™ Characters

Add more iconic Star Wars moments to your islands with new playable characters in the Hero device, spanning new eras and factions. Players can transform into them and unlock power-ups, boss battles, roleplaying, and more.

Build your storyline around these new boss-level characters, each with a fully loaded inventory:

• Luke Skywalker

• Obi-Wan Kenobi

• Mace Windu

• Kylo Ren

• IG-11

• Moff Gideon

• Boba Fett

To learn more, see Hero Device. 

Custom Weapon Templates Now Available —Pistol, SMG, Assault Rifle, and Shotgun

There’s now a way to customize weapons with Scene Graph. You can add a new Entity Prefab to your island and choose from these baseline weapon templates:

• Pistol (pistol_template)

• Sub Machine Gun (sub_machine_gun_template)

• Assault Rifle (assault_rifle_template)

• Shotgun (shotgun_template)

Reshape how each weapon looks, sounds, and plays with these four new weapon templates, making them feel purpose-built for your experience.

• Presentation Properties: Swap out the mesh, effects, and sounds to give each weapon a unique visual and audio identity.

• Balance Properties: Tune damage, fire rate, spread, and recoil to give each weapon a distinct gameplay feel.

To learn more, see Weapon Templates.

Persisting Scene Graph Data with Verse

To ensure entities in your islands, like the weapon templates and Star Wars lightsabers, persist correctly across player sessions, you must use the Verse persistence feature. These entities are not compatible with older saving methods, like the Save Point device. 

To learn more, see Using Persistable Data in Verse and Verse Persistence Best Practices.

Level up your Island's Mobile Experience

Touch Controls, Gesture Support and HUD Controls (Experimental)

Make genres like puzzle games and tycoons mobile-friendly with new features for mobile development. Now available in Experimental.

• Touch Input Gestures (Virtual Pointers): The Gesture Input API supports tap and drag inputs, unlocking more complex touch interactions on mobile devices.

• Developer Customizable Touchscreen Controls: You can build a touch layout as a UMG User Widget with Touch Control Layout Override widgets for each action (Jump, Shoot, Reload, Aim, Crouch, Sprint, and more), and then assign it to a HUD Controller device to reposition, restyle, or hide individual buttons.

  Touchscreen controls for disabled Verse inputs are hidden by default. If you unsubscribe from a default action in Verse, the engine automatically hides the corresponding touchscreen button.

• Tappable Custom HUD Widgets: A custom HUD widget can now act as a touchscreen button. Use it to drive logic from gem counters, reward notifications, inventory icons, and similar HUD elements. You can also repurpose default actions your experience doesn't use.

• Platform Controls Query: A new Verse API detects whether a player is on a touch-enabled device and which controls are relevant for that platform, so you can route players to the appropriate experience for their platform.

Learning Content

We've published Designing for Mobile, a new guide that includes principles and best practices for designing mobile games in Fortnite with UEFN. Learn what makes a great mobile experience and how to use UEFN's latest tools to build one.

Stability and Asset Management Tools

Spatial Profiler Workflow Improvements

There’s a new Monitor Performance checkbox in the Launch Session menu, which you can use to monitor your island's memory usage without opening the Spatial Profiler window.

This includes: 

• A memory health status that is visible in the UEFN status bar, as well as toast notifications when memory usage exceeds recommended levels for sustained periods.

• A new Memory Snapshot panel, which you can open from the memory usage indicators mentioned above. This panel surfaces a breakdown of the estimated memory cost of assets directly linking to any actors that reference them. The breakdown helps bridge the gap between performance alerts and what is loaded in memory.

For more information, see Memory Snapshot and Spatial Profiler.

Asset Health Tooling

New asset validation warnings now flag and report static meshes that exceed 30k vertices for LOD0. This check helps you make sure your islands run optimally on lower-end platforms.

To avoid errors associated with uploading memory intensive assets, review the requirements and guidelines here: Simplify Static Meshes.

Update: Follow a Developer on Exit Flow

In v40.40, we added the option for players to follow a developer in the Exit sidebar when leaving an island. With v41.10, we will introduce the previously announced change to remove the Follow a Developer button from the Developer Profile Link device—the device itself will still be usable and existing follower counts are not affected.

These updates give players a consistent way to follow their favorite developers across Fortnite and prevent differences in how developers use the device influencing follower counts. 

If you direct players to the device to follow your profile today, you'll need to update those callouts before v41.10.

Skeletal Animation in Scene Graph (Experimental)

An early Experimental version of the Skeletal Animation API is available to try out in this release. Using the new experimental PlaySkeletalAnimation Verse API, you can play skeletal animations directly on Scene Graph entities. Animation becomes a composable part of your entity alongside meshes, VFX, sound, and Verse logic. You can build modular animated characters and props once, and drive them at runtime with Verse. 

The API is limited for now, but is expected to expand over time. You can’t publish islands using this feature yet. To learn more, see Skeletal Animation in Scene Graph.

New Session Monitoring and Publish Readiness Tools

Live Edit and Iteration Improvements

With Live Edit, edit operations update the active session automatically, no manual push required. This release expands Live Edit support and makes in-session iteration more transparent.

Starting with 41.00, Push Changes incrementally cooks only the modified parts of your project. Previously, each push triggered a full project cook. This change reduces iteration time when updating your session. Additional asset types now support Live Edit, including Sound Control Bus Mix and Level Sequence assets.

The improvements also include:

• Edit List Panel - New panel that displays all edit operations in real time, showing which changes are already live in the session and which still require a push.

• Launch Session Button - Consolidates Push Changes, Push Verse Changes, and Refresh Session into a single control. A Verse icon badge on the Push Changes button indicates when code changes are pending.

• Start Game Button - Moved into the Session status area.

• Pause and Restart Buttons - New buttons available during Game Mode.

• Operations - New section in the Session dropdown provides one-time session actions like Push Verse Only and Validate Project.

• Live Edit Status - New status column in the Outliner, which indicates what assets require a push.

• Session Camera Controls - Has moved to the viewport toolbar and now supports camera bookmarks from the Editor, as well as in-session teleportation.

To learn more, see Live Edit and Iteration Improvements.

Session Inspector

Gain insight into the Live Edit workflow with the Session Inspector tool. This UEFN status and debugging tool provides visibility into the process of launching a session and live editing your project. 

You can use to the tool to: 

• Monitor the specific state of cook jobs for a project's modules.

• Get quick links to the Module and Cook job status in Content Service.

• Provide an at-a-glance view of the current project's dependencies.

To learn more, see UEFN Session Inspector. 

Publishing Report

We added the publishing validation workflow into UEFN to streamline the publishing process. You can prepare your island with the Publishing Report tool in UEFN. The new panel surfaces potential issues with your island before publishing. It provides a single place to evaluate publish viability against a required checklist of project requirements.

Verse Warning

In this release, we’ve improved the Verse warning that may appear when you open a project. The warning panel now lists each issue individually, and includes a button that opens the relevant location in VS Code.

After all issues have been resolved, the project can be compiled successfully and is ready to work on again.

Editor Gizmo System

We're introducing a new Editor Gizmo System designed to deliver a more consistent and flexible interaction experience across the editor. Built on top of the Interactive Tools Framework, the new system consolidates multiple legacy gizmo implementations into a single framework used across viewports and tools. This unification improves reliability, interaction consistency, and extensibility for developers building tools within the editor.

The redesigned gizmos also include a range of visual and usability improvements inspired by workflows familiar to artists and level designers from tools like Maya and Blender. With improved hit targets, clearer visual feedback, customizable interaction presets, and enhanced precision controls, the new system provides a faster and more predictable workflow for manipulating objects and assets. 

Find more details on the Editor Gizmo System and other editor improvements introduced in v41.00 in our forum post.

Physics UI Update

The option to enable Physics in UEFN has moved from under Beta Access in the project settings to the Island Settings under the World section.

When enabled, your island runs a physics simulation, creating dynamic environments where assets respond to gravity, collisions, and forces. To learn more, see Getting Started with Physics. 

Illegal Property Override Warnings Are Now Errors

In v40.00, we fixed a bug that caused incomplete hidden property validation, which produced "Illegal property override" warnings for some properties. These warnings are now errors as of v41.00.

What this means:

• New or updated islands with illegal property errors are blocked from publishing.

• Current published versions where the warning appeared will stay live.

Content Browser and Inventory Updates

Community Events

Starting June 8, you can create events to feature in your Fortnite Communities and share in-game. Your promotion options depend on where you’re hosting: YouTube or Twitch livestreams can be promoted in Communities, while Fortnite events can reach your community both in Communities and directly in Fortnite. 

Event is a new option in the More options section of the Community Post editor. Use the rich text editor to put extra details in the post that shows up in Communities.

Events in-game will be shown in several places:

• The Following tab for users following you or who have favorited your island

• Your Profile page

• Your Island page

• Your island Lobby (when the option is enabled)

The Discover row surfaces events based on when they are starting and how many players have selected that they are “Interested” on the Communities post. Placement in the row is not guaranteed, and we prevent islands and developers from appearing more than once. For upcoming events, players can mark that they are “Interested”.

To learn more, see Creating Content and Designing a Successful Event.

• Fixed a crash that could happen if Mesh to Collision tool was run on multiple meshes before any similar tool.

• Removed the "Depth" property from sculpt brushes where it had no effect (Flatten, Fixed Plane) or an undesirable effect (Move, Grab, Grab Sharp).

Visual Effects

Fixes:

• Fixed an issue where fog could be applied incorrectly to volumetric clouds in splitscreen or stereo views, causing artifacts against the sky near the edges of objects.

• Fixed an issue where falling effects remained on the Newton pawn after sliding.

Physics

Fixes: 

• Fixed an issue where players did not stay crouched when transitioning from sliding to walking without input. The crouched state is now maintained correctly.

• Fixed an issue where players fell at an unexpectedly slow speed when gliding on an island with extreme negative gravity. Glide speed now reflects the island's gravity setting correctly.

• Fixed an issue where players snapped back to a standing position after falling while crouching. The crouched state is now preserved correctly during falls.

• Fixed an issue where players' heads clipped below the water surface while swimming. The player now swims at the correct depth.

• Fixed an issue where the Prop Mover applied multiple damage ticks on a single collision. Only one damage tick is now applied per collision event.

• Fixed an issue where landing on a Launch Pad while gliding did not launch the player correctly. The Launch Pad now triggers as expected when landing in glide mode.

• Fixed an issue where the idle swimming animation did not play when moving upward inside a water volume. The animation now plays correctly in all swim directions.

• Fixed an issue where every other bounce on a D-Launcher did not allow the player to deploy their glider. The glider can now be deployed after every bounce.

Scene Graph

New: 

• Updated the Entity Prefab Editor where selecting a sub-prefab now highlights all of its entities, including entities added in that sub-prefab instance.

• Entity Prefabs: creating a new prefab now prompts you to choose a base class.

• Turned on prefab thumbnails by default.

Fixes: 

• Fixed an issue where transforms were applied twice in the entity hierarchy in the Prefab Editor.

• Fixed an issue where using { /UnrealEngine.com/SceneGraph } incorrectly compiled in Verse. Projects using this path will no longer compile. You can use using { /Verse.org/SceneGraph } instead.

• Fixed an issue where updating an asset thumbnail could mark the Entity Prefab as modified unnecessarily.

Verse Updates and fixes

API

New:

• Added GetGlobalTransform to positional.

• Added @doc to Verse rotation.

• Added the fort_vehicle API:

  • Replaced GetOccupants() with GetPassengers(), which returns all agents currently in the vehicle.

  • Added AddAgent(InAgent:agent) to forcefully seat an agent in the vehicle.

  • Added RemoveAgent(Agent:agent) to forcefully remove a specific agent from the vehicle.

  • Added RemoveAll() to forcefully remove every agent from the vehicle.

  • Added GetSeats():[]fort_vehicle_seat, which returns the vehicle's seats.

• Added fort_vehicle_seat, a new interface for vehicle seats:

  • Occupant:?agent — the agent currently in the seat, if any.

  • Vehicle:fort_vehicle — the vehicle that owns this seat.

  • InsertAgent(Agent:agent, Seat:int) — seats an agent in a specific seat.

  • IsDriverSeat() — succeeds if the seat is a driver seat.

• Added IsWeakpointDamage property to damage_result Verse API.

Language

Fixes:

• Fixed an issue in digest generation so that using statements and qualifiers respect module @available annotations.

• Fixed two cases where expressions were incorrectly judged not to suspend and so were not accepted as structured-concurrency subexpressions: when the suspension is in a tuple subexpression, and when it is in the initialization of a var.

• Disallowed @editable on fields that are instances of type variables, since the editor cannot yet enforce that the set value is of the correct type.

Tools

New:

• Updated error strings for asset parameters so they always appear in the digest notes, since inline comments in class definitions are purged when generating the digest.

Fixes:

• Fixed an issue where referenced Verse classes were not cleaned up properly.

• Updated an error popup message to be more representative.

Unreal Revision Control & Notes Updates and fixes

Fixes: 

• Fixed an issue where excessive debug logging flooded the log output.

• Fixed drag input in the Branch Explorer remaining active after the cursor left the window bounds.

• Fixed an issue where long branch names overflowed the tooltip's background.

• Fixed an issue such that the sync latest button and clock icon now correctly reflect state when changes were brought in from an earlier revision.

• Fixed an issue that caused intermittent failures and unexpected results when merging one branch to another.

Branch History Panel

New: 

• The Merged revision control status icon color has been updated for improved legibility.

Fixes: 

• Fixed the Branch History tab incorrectly highlighting the left-side line for non-synchronized revisions.

Performance

New: 

• Some source control operations in the editor can now run in parallel, improving performance.
