Show the in-memory session settings (umodel exe, game directory, output directory, AES keys). No config file is used; settings live only for this server session.

Store settings in the in-memory session (nothing is written to disk). NOTE: most values (gamePath/gameTag/aesKeys/pakAesKey/pakAesMode) are auto-remembered whenever you pass them to any tool, so you rarely need this tool — use it only to set values ahead of time, clear them (empty string), or configure pure settings: umodelExe (user-confirmed), outputDir, pakAesMode. IMPORTANT: umodelExe and gamePath must come from the user — ask the user for the umodel executable path and the game/pak directory before setting them; never guess. Only fall back to umodel_find_exe when the user does not know the path or the given path is wrong. Pass an empty string to clear a field. outputDir defaults to the Downloads folder when unset.

Search common locations (Downloads/Desktop/Documents/Program Files/PATH...) for umodel executables (umodel.exe, umodel_64.exe, or custom builds like umodel_acl_*.exe). ONLY use this as a fallback when the user does not know the umodel path or provided an invalid one — always ask the user for the path first. With verify=true the newest candidate is tested via -version and remembered. IMPORTANT: different umodel builds/versions support different games (e.g. umodel_acl variants). If more than one candidate is found the remembered exe stays UNCONFIRMED and per-game tools refuse to run until you show the candidate list to the user, ask which version to use for the target game, and confirm it via umodel_session_set { umodelExe }. Never pick a version yourself.

Run 'umodel -version' to verify the executable works. Pass exe to test a new path; if it works it is remembered in the session.

List games supported by umodel. With tags=true shows the short tags usable with -game=/gameTag. Check this BEFORE any list/export/save call: if the user's game appears (e.g. Roco Kingdom: World -> roco), remember it via umodel_session_set { gameTag } so later calls don't pop the blocking engine-version GUI dialog.

Recursively scan a directory for Unreal package files (.pak/.upk/.uasset/.ut2/...) so you know what to pass to other tools. The directory should come from the user — ask which game directory to unpack before scanning.

Run 'umodel -list ' to list objects contained in a package.

Run 'umodel -pkginfo ' to display package summary (name table, export table).

Run 'umodel -export' to convert assets (meshes, textures, animations, sounds...) to standard formats (psk/gltf/tga/png/...). Without object filters the whole package is exported. Output defaults to the Downloads folder. IMPORTANT: cooked UE4/5 games need a gameTag, otherwise umodel pops a blocking engine-version GUI dialog. ALWAYS call umodel_game_list { tags: true } FIRST and use the official tag if the game is listed (e.g. roco); the server blocks the call and reminds you if gameTag is missing.

Run 'umodel -save' to copy raw package files (.upk/.uasset + .uexp/.ubulk) out of a game directory, e.g. to unpack a cooked game without converting. Output defaults to the Downloads folder.

Parse UE .pak index files (AES-encrypted indexes supported, including games using custom bit-flipped AES) and list asset paths matching the filters. Works without umodel. Use this before pak_extract to locate assets (meshes/textures/animations). The pak directory should come from the user — ask which game directory to unpack first.

Extract raw .uasset/.uexp files from UE .pak archives by parsing the index directly (AES-encrypted indexes supported, including custom bit-flipped AES). Works without umodel. The extracted loose files can then be converted with umodel_export (point it at the output directory). Output defaults to /pak under the Downloads folder.

List the folder structure and files produced by umodel_export/umodel_save, with sizes. Use this after an export to see what was unpacked.
