General Physics Beta Is Coming Soon (v37.40)
With the Beta release of General Physics coming in v37.40, you’ll be able to publish your physics-enabled islands. Physics provides mechanics for your players to push, topple, hit, and move objects, unlocking emergent physics-driven gameplay. Create experiences that feel more realistic, engaging, and predictably unpredictable. Don't wait! Get your island physics-ready!
To learn more about using the feature in your islands, see the Physics documentation.

New Multi-Island Monetization Dashboard in Creator Portal
When you click the Monetization tab in your main navigation, you’ll now find a brand-new multi-island Monetization dashboard. We’ll continue to expand it with multi-island analytics over time.
Please note that the legacy analytics site will sunset on November 3, 2025, and all monetization metrics will be accessible directly from your Creator Portal account navigation.
Fab in Launcher UEFN Update
The Import from Fab page highlights new workflows for using the in-editor application to search and import assets to help build your islands. The workflow includes the new application through the Epic Games Launcher, called Fab in Launcher.
User Interfaces Feature Template
The User Interfaces Feature Template now includes an example of adjusting the experimental player input to create custom keybinds and UI for your island.
The template utilizes the Keybind User Widget and the Verse file hud_keybind_demo_device.verse to create the custom keybinds. To learn more about creating and binding these features for reloading, shooting, crouching, and standing, see User Interface Devices.
The template is accessible from the UEFN project browser, under the Feature Examples tab.

Community Bug Fixes
The following fixes are from issues that you submitted to us on the forums. Thank you for your patience and for reporting these issues!
Fixed an issue where UEFN would need to be restarted after losing connection to Unreal Revision Control.
Fixed an issue where the Pop-Up device, “Do Not Close on Button Press,” did not work as intended.
Fixed an issue where Weapon Canting was not working on published islands.
Fixed an issue with the Item Spawner where the base visibility was disabled, but the spawned item would remain stuck in place.
Device Updates and Fixes
New:
Added ViewModels for the Voting Group device and Voting Option device. These are still under development and not yet functioning with the device.
Added a configurable user option for when the Skilled Interaction device should hide its UI — either when the player's own interaction completes (existing default behavior) or when all queued interactions complete (new behavior).
Fixed an issue where players couldn't enter the top half of Skydive Volumes.
Added a user option to hide the beacon for the Changing Booth device.
Fixes:
Fixed an issue where the Launch Pad wouldn't account for device rotation when launching the player.
Fixed issue with the Voting Option device where trying to vote for an option more than once did not produce an error.
UEFN Updates and Fixes
New:
Added support to drag assets into the outliner to create entities.
Added support to drag assets into the entity prefab editor viewport to create entities.
Added symmetry support to the Paint Vertex tool.
Added an experimental setting for entity prefab in place editor mode.
Fixes:
Fixed a potential infinite loop in the serialization of packed integers when loading malformed values.
Fixed the Gameplay Events for Sequencer not showing the Gameplay Event Function property for Trigger, Enable, Disable, and Reset Times Triggered.
Resolved playback errors and crashes for Mesh Plate actors configured as spawnable in Sequencer after saving or reloading the level or level sequence.
Fixed a crash that occurred when force-deleting an entity prefab.
Fixed an editor crash when saving a map while the landscape material was invalid.
Fixed landscape weight blending that sometimes left ghost layer masks.
Fixed a variation of the issue where swapping teams would cause random disguises to revert to a different player’s random disguise. This issue is fully fixed in v37.40.
Fixed template hyperlinks in the Project Browser that were linked to deprecated documentation sites.
Scene Graph
Fixes:
Fixed child entities that were derived from a prefab so they cannot be reparented anymore.
Fixed the introduction of CanParent utility functions for entities.
Verse Updates and fixes
Fixes:
Updated variables declared in default initializers to be local to the initializer expression.
Depreciations:
Deprecated operations like
vardeclarations and reads in initializers. Verse class member default initializers currently must be<reads><converges>, aside from instantiating other objects.
Unreal Revision Control (URC)
Fixes:
Fixed an issue causing frequent reports of the error message
Request put failed: Server returned error 3…// Failed to store fragments, remote error….
