The V2 in-game mod browser is a utility surface for finding, previewing, installing, and updating mods without leaving the game. The browser is driven by FV2ModBrowserViewModel in V2Modding and rendered through UV2ModBrowserScreen in V2UI.

Workspace#

The browser model keeps the working surface dense and predictable:

  • FV2ModBrowserFilter carries search text, category, tag, provider, sort mode, installed-only, updates-only, and compatibility filters.
  • FV2ModBrowserEntry carries display metadata, provider ids, preview media, rating/download/updated signals, install state, and install/update eligibility.
  • FV2ModBrowserPreview exposes the selected entry, preview media flag, and actions.
  • FV2ModBrowserViewModel exposes rows, result counts, selected row, installed count, update count, keyboard/gamepad support, and install/update-in-game support.

The default widget target is /Script/V2UI.V2ModBrowserScreen with screen id Mods.Browser.

Search, Filter, Sort#

ApplyModBrowserFilter filters against display name, author, summary, category, and tags. Provider, category, required tag, installed-only, updates-only, and compatible-only filters are applied before sorting. Supported sort modes are relevance, name, downloads, rating, and last updated.

Preview And Actions#

BuildModBrowserPreview creates install, update, enable/disable, rating, and details actions from the selected row. Install and update actions are primary actions and mark that a download is required, so provider-specific Steam Workshop or mod.io flows can be launched from the same screen.

Native Screen#

UV2ModBrowserScreen configures from the view model, exposes rows and preview state to Blueprint, applies new filters, updates selection, and reports support for cardless operational layout, keyboard/gamepad navigation, and install/update without leaving the game.

Verification#

Run:

bash
python3 V2/ue/Tools/check-v2-mod-browser.py
python3 -m json.tool V2/ue/Content/V2/Modding/ModBrowser_V2_Contract.json

The focused checker verifies runtime types, filtering/sorting/action helpers, the native UI screen, automation assertions, docs, CI/Horde wiring, and TODO evidence for 72.14.2.3.
