Troubleshooting steps for Hello Neighbor Mod Kit stuck at 45%:
If you want, paste any error text or a screenshot and I’ll suggest targeted fixes.
To fix the Hello Neighbor Mod Kit getting stuck at 45% on the loading screen, the most common solution is to simply wait it out.
This behavior is completely normal for the software. Below is a complete article explaining exactly why this happens and how to troubleshoot it if the freeze is permanent. 🛠️ How to Fix Hello Neighbor Mod Kit Stuck at 45%
If you have downloaded the Hello Neighbor Mod Kit to start creating custom maps and gameplay, you will likely encounter a frustrating hurdle: the loading screen freezes at exactly 45%.
This is one of the most common issues reported by creators in the community. Fortunately, it is usually not a bug or a broken installation. 🧠 Why Does it Freeze at 45%?
The Hello Neighbor Mod Kit is built on Epic Games' Unreal Engine 4. In Unreal Engine, 45% is the exact point where the software begins compiling shaders.
Shaders are the code programs that tell the engine how to render surfaces, lighting, and shadows. Because the Mod Kit contains a massive library of game assets, textures, and lighting data, there are thousands of shaders that need to be processed the very first time you launch the editor. 🚦 Step-by-Step Troubleshooting 1. Give it Time (The Primary Solution)
The absolute best solution is patience. Depending on your computer's processing power, the initial shader compilation can take anywhere from 10 minutes to over an hour.
The fix: Leave the Mod Kit open and do not click on the window (which might prompt Windows to say the program is "Not Responding").
The good news: This massive wait time typically only happens during the very first launch or after a massive update. Future launches will be much faster. 2. Verify System Activity via Task Manager
If you want to make sure your computer hasn't actually crashed, you can check your hardware activity: Press Ctrl + Shift + Esc to open the Windows Task Manager. Look at your CPU usage percentage.
If the CPU usage is spiked at 90% to 100%, or if you see several background processes called ShaderCompileWorker, the editor is working perfectly. It is utilizing your processor to build the assets. Do not close it! 3. Check Dedicated GPU Requirements
Unreal Engine 4 is a heavy development environment. If your computer relies solely on integrated graphics (common in non-gaming laptops) instead of a dedicated graphics card (like NVIDIA or AMD), the editor may genuinely fail to load past this point.
Ensure your PC meets the basic system requirements to run game development software. 4. Clear Your Cache & Reinstall (Last Resort)
If you have waited for several hours and the Task Manager shows 0% CPU activity pointing to a hard freeze, you may need to clear out corrupt files: Back up any mod files you have already started. Uninstall the Mod Kit.
Press Windows Key + R, type %localappdata%, and delete any saved Unreal Engine or Hello Neighbor Mod Kit folders to clear broken cache files. Reinstall the kit and try launching again. Updated Modkit freezes at 45% loading (SOLVED) hello neighbor mod kit stuck at 45
In almost every case, being stuck at 45% is not a crash; it is the Unreal Engine compiling shaders in the background.
Why 45%? This is the specific point where the engine begins loading and compiling core shaders.
How long? Depending on your CPU, this can take anywhere from 10 minutes to several hours. Verification: Open your Task Manager (
) and look for processes named "ShaderCompileWorker.exe". If you see them using high CPU, the mod kit is working—just be patient. 2. Verify Hardware Compatibility
The Mod Kit is much more demanding than the actual game. If your system doesn't meet the requirements, the editor may never finish loading. [Solved] Unreal Editor loading stuck at 45% - C++
The Hello Neighbor Mod Kit appearing "stuck" at 45% during the loading screen is a common occurrence caused by the Unreal Engine 4 backend compiling shaders for the first time
. While it looks frozen, the engine is actually processing a massive amount of visual data in the background. Unreal Engine Why it Stops at 45% In many Unreal Engine projects, including this mod kit,
is the specific threshold where the editor initiates shader compilation. Shader Compilation
: The software is translating graphics code into a format your specific video card can understand.
: This process is highly demanding on your processor. You can verify it is still working by opening Task Manager
(Ctrl+Shift+Esc); you should see "ShaderCompileWorker" processes active and high CPU usage. First-Time Load
: This extreme delay typically only happens during the very first launch after installation or after a major update. Unreal Engine Expected Wait Times
Wait times vary wildly based on your hardware specifications: High-End PCs (e.g., 512GB+ SSD, modern CPU) : May load in 5–10 minutes Mid-Range PCs : Can take between 50 minutes and 5 hours Lower-End Systems
: Users have reported it taking significantly longer, sometimes appearing to hang for hours. Unreal Engine Recommended Solutions The "Wait it Out" Method
: The most effective solution is simply to let the program run. Do not close the window, as this resets the compilation progress. Check for Crashes
: If the loading screen disappears or an error message pops up, it has actually crashed. If it remains at 45% with a spinning icon or high CPU usage, it is still working. Firewall Permissions Troubleshooting steps for Hello Neighbor Mod Kit stuck
: Ensure your firewall isn't blocking the editor or the shader workers. Some users found success by giving the Unreal Editor full permissions. Hardware Limitations
: If you do not have a dedicated GPU, the editor may fail to launch entirely or perform so poorly that it effectively stays frozen. Unreal Engine
Has the loading screen been at 45% for more than 5 hours, or do you see any specific error messages?
When the Hello Neighbor Mod Kit gets stuck at 45% during loading, it is almost always compiling shaders
. This is a normal part of how the underlying Unreal Engine 4 works, especially during the first launch after installation or after an update. Unreal Engine Immediate Solutions Wait it out
: Depending on your PC's hardware, this process can take anywhere from a few minutes to over an hour. Check Task Manager Ctrl + Shift + Esc and look for "ShaderCompileWorker"
processes. If they are active and using your CPU, the program has not crashed—it is just working through a large amount of data. Fix Firewall issues
: Sometimes a firewall can block the initial setup. On Windows, you may need to temporarily turn off Windows Firewall
or ensure the Epic Games Launcher and Mod Kit have permission to run. Unreal Engine Troubleshooting Steps Clear Save Data
: If the kit continues to freeze on subsequent launches, navigate to the folder with the mod kit, then go to Hello Neighbor -> Saved -> SaveGames delete the files Verify Hardware
: The Mod Kit requires a dedicated GPU to run effectively. If you are using integrated graphics (common on older laptops), it may hang indefinitely or perform very poorly. Disable XGE
: If you are familiar with config files, some users find that disabling the XGE shader compilation in the engine's configuration can resolve persistent 45% hangs. Unreal Engine How long has the loading bar been sitting at 45% for you? Updated Modkit freezes at 45% loading (SOLVED)
If your Hello Neighbor Mod Kit is stuck at 45% on the loading screen, don't worry—this is a well-known behavior of the Unreal Engine (UE4) that the kit runs on. In almost all cases, the kit is simply compiling shaders in the background, which can take a significant amount of time during the first launch or after an update. 🛠️ Common Fixes & Troubleshooting How to fix Unreal Engine 4.18.1 stuck at Initializing 45%
When the Hello Neighbor Mod Kit gets stuck at it is almost always because the Unreal Engine is compiling shaders
. This is a normal part of the initial startup process, especially after an update or the first time you launch the kit. Unreal Engine To resolve this or verify if it's working: Be Patient
: This process can take a very long time (sometimes over an hour) depending on your CPU speed. Check Task Manager Ctrl + Shift + Esc . If you see ShaderCompileWorker Restart and retry
processes running and high CPU usage, the mod kit hasn't crashed; it’s just working in the background. Firewall Permissions
: Ensure your firewall isn't blocking the application. Some users found that disabling the firewall or adding an exception for Unreal Engine allowed it to proceed. Hardware Limits
: If you are using a laptop without a dedicated GPU or have very low RAM, the editor may take significantly longer to load or might fail to launch entirely.
