If it gets stuck at 45% specifically during "Compiling Shaders":

The Mod Kit was built on Unreal Engine 4.19, which sometimes hates newer DX12 cards.

If you're still stuck, consider reporting the issue on forums or comment sections of the mod's page. Provide details like:

Example: "Hi, I'm having trouble with the Hello Neighbor Mod Kit. It gets stuck at 45% installation. I've tried reinstalling, updating my game, and disabling other mods. I'm on PC, Windows 10, with the latest game and Mod Kit versions. Any help?"

When the Hello Neighbor Mod Kit (built on Unreal Engine 4) appears stuck at 45% during loading, it is usually not a crash but a heavy background process. Primary Cause: Shader Compilation

The 45% mark is the specific point where the engine begins compiling shaders. This is a critical process that translates graphics code for your specific hardware.

Waiting is Required: Depending on your hardware (CPU and RAM), this can take anywhere from 5 minutes to several hours.

First Launch/Updates: This happens most frequently during the first launch after installation or after a major engine update.

Resource Usage: Your CPU usage may spike to 100% while this happens as "Shader Compile Workers" run in the background. Recommended Fixes & Solutions

If you have waited more than an hour without progress, try the following steps:

Monitor Task Manager: Press Ctrl + Shift + Esc to open the Task Manager. Look for processes named ShaderCompileWorker.exe. If these are active and using CPU power, the Mod Kit is still working and you should let it continue.

Verify Hardware Specs: Systems without a dedicated GPU or with less than 8GB of RAM may struggle to complete this process at all. hello neighbor mod kit stuck at 45

Check Your Firewall: Sometimes firewalls block the engine's initialization processes. Try temporarily turning off your firewall or adding the Mod Kit as an exception.

Disable XGE (Advanced): If you have "Incredibuild" or "XGE" installed, it can sometimes stall the process. You can manually disable it by editing ConsoleVariables.ini in your Unreal Engine config folder and setting r.XGEShaderCompile = 0.

Delete Save Files: If the kit has worked before but is now stuck, navigate to your Mod Kit directory (Hello Neighbor/Saved/SaveGames) and delete existing save files that might be corrupted or causing loading issues.

Install Latest Unreal Engine: Ensure you have the latest version of the Unreal Engine installed via the Epic Games Launcher, as some users reported this resolved stuck installs.

: 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.

In almost every case, being stuck at 45% is not a crash; it is the Unreal Engine compiling shaders in the background. Right-click the

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 The Mod Kit was built on Unreal Engine 4

: 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

: 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?

It seems you're having trouble with the "Hello Neighbor" modding community's creation, "Mod Kit," getting stuck at 45%. This issue could stem from several places, but without specific error messages or more details about your setup (like the platform you're playing on, any mods you've recently installed, etc.), providing a precise solution can be challenging.

However, I can offer a few general troubleshooting steps that might help:

This bypasses permission issues and potential sector errors on the specific drive.

Do not try these out of order. Start with Step 1, and stop when the problem is solved.
