[Bug] UEFN_Button_Loud — Controller/Gamepad buttons completely unresponsive in UMG Widget (latest UEFN version)

Summary

Controller/gamepad users cannot interact with any UEFN_Button_Loud buttons in UMG Widget Blueprints. Mouse on PC works perfectly. 8 UMG widgets with 8-22 buttons each inside Scroll Boxes. All buttons have Is Focusable = true, ui_input_mode.All is set, SetFocus() is called. UEFN_Button_Loud has no Navigation section in Details panel — cannot configure D-pad navigation rules. Related to FORT-621416 (partial fix in v34.40) but issue persists on latest UEFN version. See also: Verse UI's huge un focus problems with controllers

Steps to Reproduce

  1. Join island 3466-1384-6409 with a gamepad/controller
  2. Open the weapon shop (press the button device or walk into trigger zone)
  3. Attempt D-pad navigation or press A/X on any button
  4. Try opening Fortnite menu and closing it, then retry button interaction

Expected Result

First button should receive gamepad focus automatically. D-pad should navigate between buttons in the grid. A/X should activate the focused button. Player should be able to navigate between weapon Scroll Box and category Scroll Box using D-pad.

Observed Result

No button receives focus. No button can be pressed with gamepad. D-pad does nothing. Player is soft-locked in UI — cannot interact or close the shop. Only mouse click on PC works. Issue confirmed on console by another player.

Platform(s)

All consoles (PlayStation, Xbox) and PC with gamepad. PC with mouse works correctly.

Additional Notes

Project: TestProgekt

Technical details:

  • 8 UMG Widget Blueprints (Shotguns, Assault Rifles, SMGs & Pistols, Sniper Rifles, Consumables, Explosives, Ready to Play, Now Available)
  • Each widget: UEFN_Button_Loud buttons inside Scroll Box + second Scroll Box with category navigation
  • Widgets preloaded at start with Hidden visibility
  • Category switch: HideAll() → RemoveWidget() → AddWidget() → SetVisibility(Visible) → SetFocus()
  • Tried SetVisibility-only toggling (no Remove/Add) — same result

Key finding: UEFN_Button_Loud does not expose a Navigation section in the Details panel, unlike standard UE5 Button. There is no way to configure Up/Down/Left/Right D-pad navigation rules, and no Verse API exists to set them programmatically.

Questions:

  1. How to configure gamepad navigation for UEFN_Button_Loud without Navigation section?
  2. Is there a Verse API for setting focus navigation rules?
  3. Is UEFN_Button_Loud inside Scroll Box supported for controller input?
