Features

Mod Management

• Install .zip, .rar, .7z, .pak, .ucas, and .utoc archives, including .pak-x, .ucas-x, and .utoc-x variants.
• Organize mods with tags, descriptions, previews, favorites, collections, and bundles.
• Enable, disable, back up, and check for updates. Updates keep their current install location.
• Review installs before writing, including destination folders and files that will change.

Game Profiles

• Auto-detect Unreal Engine games and keep a separate profile for each.
• Detect engine versions and support ~mods, mods, or LogicMods folder layouts.
• Launch a game with the selected profile and runtime in place.

Nexus Mods

• Browse, search, filter, and sort the Nexus Mods catalogue without leaving the app.
• Sign in with OAuth and PKCE, or use a manual API key.
• Download through the manager, handle nxm:// links, and check installed mods for updates.
• Queue downloads with pause, resume, and progress tracking.

Conflict Detection

• Scan installed mods for file-level overlaps before launch.
• Group colliding mods, list affected files, filter by file type, and search results.
• Copy a summary, export JSON, or open the selected conflicts in the Assets Viewer.

Assets Viewer (PakViewer)

• Mount .pak and IoStore archives, with mapping files, AES keys, and per-game engine versions.
• Browse assets, preview textures, materials, audio, and code, and inspect static, skeletal, and physics meshes.

• Conflict Dashboard for per-mod collision summaries and reports.

Avalonium Runtime

• In-game menu with live object inspection, editing, function calls, watches, and universal search.
• Developer console with command unlocking and level-transition safety.
• Lua, Blueprint, and native C++ mod support.
• Built-in mods: HUD toggle, performance panel, Blueprint loader, shared events, and Lua helpers.
• Structured logs and optional crash reports.

Creator Tools

• Generate compilable C++ SDKs and .usmap mapping files.
• Export type data, class relationships, dependency graphs, and console reports.
• Validate SDKs against the running game, generate project files, and compare SDK versions.
• Discover and verify AES archive keys when a game uses them.

Interface

• Four themes: Glassmorphic, Crimson, Cozy, and Wavey.
• Custom accent, navigation, and interface colors.
