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.

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.

Troubleshooting: Hello Neighbor Mod Kit Stuck at 45% If you are trying to launch the Hello Neighbor Mod Kit and the loading screen seems frozen at 45%, you are not alone. This is one of the most common issues reported by creators in the community.

While it looks like a crash, it is almost always a normal part of how the Unreal Engine—which the Mod Kit is built on—operates. Below are the primary reasons this happens and how you can fix it. 1. The Main Reason: Shader Compilation

The 45% mark is exactly where the Unreal Engine starts compiling shaders.

What is happening? The engine is translating thousands of graphics files into a format your specific graphics card (GPU) can understand.

Why does it stop at 45%? This is the stage where the engine initializes its core resources. If it's your first time opening the Mod Kit or you have recently updated it, the engine has a massive backlog of shaders to process. 2. How to Verify if It Is Still Working

Before you force-close the program, check if your computer is actually still processing the data: Open the Task Manager (Ctrl + Shift + Esc).

Look for processes named ShaderCompileWorker.exe or UE4Editor.exe.

If your CPU usage is high (often sitting at 100%), the Mod Kit has not crashed; it is simply working as fast as it can in the background. 3. Estimated Wait Times

The time it takes to move past 45% depends entirely on your PC's hardware: High-End PCs (SSD + Modern CPU): May take 5–10 minutes. Mid-Range PCs: Can take 30–60 minutes.

Low-End PCs / Laptops: Users have reported waiting anywhere from 2 to 9 hours.

No Dedicated GPU: If your computer uses integrated graphics (like many basic laptops), the Mod Kit may never finish loading or will perform extremely poorly. 4. Fixes and Workarounds If the Editor crashes while loading a specific

If you have waited for several hours and nothing has changed, try these steps: [Solved] Unreal Editor loading stuck at 45% - C++

The most frequent cause is shader compilation. When you launch the Mod Kit for the first time or after an update, the engine must compile thousands of shaders to render graphics correctly. 

The "Stuck" Illusion: The progress bar often stops at 45% because that is the point where the engine initializes the renderer and begins heavy shader work. Verification: Open your Task Manager (

). If you see multiple processes named "ShaderCompileWorker," the engine is not frozen; it is working in the background.

Solution: Simply wait. Depending on your CPU speed, this can take anywhere from 10 minutes to several hours.  2. Disable XGE Shader Compilation 

If waiting doesn't work or takes an unreasonable amount of time, you may need to disable the XGE (Incredibuild) shader compilation, which can sometimes stall the process if not configured correctly. 

Navigate to: C:\Program Files\Epic Games\UE_4.XX\Engine\Config\ConsoleVariables.ini (Note: The version folder may vary). Edit: Find the line ; r.XGEShaderCompile = 0.

Action: Remove the semicolon (;) so it reads r.XGEShaderCompile = 0 and save the file. Restart: Relaunch the Mod Kit.  3. Check System Requirements and Firewall 

If the Mod Kit never progresses beyond 45% even after hours of waiting, check your hardware and security settings: 

GPU Requirements: Computers without a dedicated GPU often fail to load the editor entirely.

Firewall/Antivirus: Security software may block the editor from creating temporary files. Try temporarily disabling your firewall or adding an exception for the Epic Games Launcher and the Mod Kit.

Clear Save Data: Occasionally, corrupted playtest data can cause hangs. Navigate to the Mod Kit folder, then to HelloNeighbor > Saved > SaveGames and delete the files inside.

Are you seeing any specific error messages or crash reports when the loading screen closes?  [Solved] Unreal Editor loading stuck at 45% - C++

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. The 45% mark is the "handshake" between the

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)

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%
