Help and troubleshooting

UE4SS didn't start. Check these in order:

1. dwmapi.dll and UE4SS.dll must be directly in Win64, next to EDFWB-Win64-Shipping.exe. Not in a UE4SS_v3.0.1 subfolder, and not in the top-level mikan folder. Part 1, step 6 shows how.
2. Install the latest Visual C++ Redistributable (x64).
3. Some antivirus programs quarantine dwmapi.dll, because it's a loader that starts another DLL inside the game. Restore it or add an exception, but only after checking that your UE4SS_v3.0.1.zip has the official SHA-256 (part 1, step 4).

• Open UE4SS.log and read its last lines: they show how far UE4SS got.
• Install the latest Visual C++ Redistributable (x64).
• UE4SS's own settings file names one switch for crashes at start: under [General] in UE4SS-settings.ini, set bUseUObjectArrayCache = false.
• To tell UE4SS and the mods apart, move the seven UngodlyEDFWorldBrothers… folders out of Win64\Mods for one test start. If the game starts then, put them back one at a time to find the one that matters, and see the questions below.

UE4SS couldn't find its way around the game's engine. That happens when a game update changes the game's code. StixsworldHD checked that UE4SS v3.0.1 finds all 7 of its anchor points in the current game, so if you see this after an update, wait for an updated release of the mods.

Experimental builds keep their files in a ue4ss subfolder, and six of the seven mods can't load on them. Move dwmapi.dll and the ue4ss folder out of the game folder as a backup and install the stable v3.0.1: Already have UE4SS?

• Check the path and spelling: Win64\Mods\<mod folder>\dlls\main.dll.
• Failed to load dll <…main.dll> for mod …, error code: 0x7f means a different UE4SS version: the mod asks for functions that this UE4SS.dll doesn't have (Windows error 127, "the specified procedure could not be found"). Install the stable v3.0.1 (part 1).
• error code: 0x7e means a file the mod needs is missing from Windows (Windows error 126, "the specified module could not be found"). Install the latest Visual C++ Redistributable (x64).
• Mod '…' disabled in mods.txt. and no enabled.txt in the mod's folder means it was switched off. Tick Start with the game on its page in the menu (or set its line in mods.txt to : 1, or put enabled.txt back), then restart the game.

• Click into the game window first, so it has the keyboard.
• Look in UE4SS.log for in-game overlay ready on the game's DirectX 11 window.
• If the log says the game is not running on DirectX 11, use Ctrl + O and the mods' tabs in the UE4SS window.
• Another overlay or tool might use the same key. Pick another key on the mod's page, or change MenuHotkey (OverlayHotkey for the AI) in its settings file.
• If you switched on UE4SS's LineTraceMod, it also reacts to F3: give World Optimization another key.

The UE4SS window opens as a separate window. In exclusive fullscreen, Alt + Tab to it, or switch the game to borderless or windowed. It needs GuiConsoleEnabled = 1 in UE4SS-settings.ini, which is the default.

Its Status tab (F4) says what it sees and why it might be waiting, and README_Beautify.md explains every status line. F2 switches it off at once. Beautify needs DirectX 11, the game's default.

Six of the mods check the game code they rely on when they start (Subtitles checks the game's subtitle widget when the game first creates it) and switch off whatever no longer matches, with the reason in UE4SS.log and in their menu pages. The game then runs as it would without them. Beautify checks the camera's near clip plane at start and shows on its Status tab what it sees of the game's drawing; if that looks wrong after an update, press F2 to switch it off.

Not for World Optimization: when you host, every player sees your extra Invaders without the mod. The other mods each work on your side only, or only on the PC that runs that part of the game. Online play at a glance lists them one by one. The AI changes the enemies your PC runs when you host, for everyone in the game, so use it with friends who know and agree.

No. None of them change game files, saves or game settings. Everything they do lives in memory while the game runs, plus their own settings files, the AI's learned_brains.txt, subtitle backlogs you choose to save, and the enabled.txt and mods.txt changes made by Start with the game.

UE4SS is open source (MIT License), and part 1 installs it only from its official GitHub release. dwmapi.dll is the loader that starts UE4SS inside the game: Windows loads it from the game's folder, and it loads UE4SS.dll. That is the kind of behaviour some antivirus programs flag. To be sure you have the original, compare your zip's SHA-256 with the one on this site.

The mirror's file was also downloaded and compared with the direct download on 11 Oct 2026: same bytes, same SHA-256. Check your own copy.

The menu needs a mouse and keyboard. While it's open, a controller keeps controlling the game, so pause first if you play with a pad. The Input mod's buffer and toggle aim work with a controller and with keyboard and mouse; its stick shaping and trigger points are for controllers.

Use the reset button on the mod's page: Reset all settings to defaults on the Overview tab of World Optimization, Voxel Destruction, Hit Detection, Input and Subtitles, and on the About tab of the AI.

Beautify's Beautify defaults button (Beautify tab) resets its Sharpen, Colour, Vignette and Dither values. To reset everything else too, close the game and delete UngodlyEDFWorldBrothersBeautify.ini: the mod writes a new one with the defaults.

Untick its master switch in the menu to get the game's own behaviour back at once, or untick Start with the game so UE4SS doesn't start it. To remove it, delete its folder. Everything is listed in Turn mods off or uninstall.

In the download: README.md for the whole collection and a README_<Mod>.md for each mod, with every setting, its range and default, performance notes, known limitations, how each mod was checked and, for every mod but Beautify, online play. Open them with Notepad.
