Hello Neighbor Mod Kit Stuck At 45 _top_ -

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

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. Unreal Engine Are you seeing ShaderCompileWorker active in your Task Manager right now? How to fix Unreal Engine 4.18.1 stuck at Initializing 45% 22 Nov 2017 —

Hello Neighbor Mod Kit getting stuck at during initialization is a common occurrence and, in most cases, is not a crash but a necessary background process Unreal Engine The Most Likely Cause: Shader Compilation

The Mod Kit is built on Unreal Engine 4 (UE4). When you launch it for the first time, or after an update, the engine must compile thousands of shaders. Unreal Engine

This is the specific point in the loading sequence where the engine begins loading and compiling core shaders. The Solution:

Just wait. Depending on your CPU and RAM, this can take anywhere from 15 minutes to over an hour . You can confirm it is working by opening Task Manager

(Ctrl + Alt + Delete) and looking for "ShaderCompileWorker.exe" processes running in the background. Unreal Engine Other Potential Fixes hello neighbor mod kit stuck at 45

If you have waited for several hours and the progress has not moved, try these alternative troubleshooting steps: How to fix Unreal Engine 4.18.1 stuck at Initializing 45%

Hello Neighbor Mod Kit getting stuck at during the loading screen is a common issue typically caused by Unreal Engine compiling shaders

. While it looks frozen, the engine is actually processing a high volume of assets for the first time. Unreal Engine Why it happens

, Unreal Engine 4 initiates shader compilation. This process is highly CPU-intensive and occurs: Upon the first launch after a fresh installation. After a major engine or project update. When clearing the DerivedDataCache Unreal Engine How to Resolve the "Hang" In most cases, the solution is

. Depending on your hardware, this stage can take anywhere from 15 minutes to several hours Unreal Engine Check Task Manager Ctrl + Shift + Esc to open the Windows Task Manager . Look for ShaderCompileWorker.exe

processes. If they are active and using CPU resources, the kit is working correctly and you should wait. Manage Firewall/Antivirus

: Sometimes security software blocks the shader compiler. Try temporarily disabling your firewall or adding an exception for the Mod Kit. Verify System Requirements

: Integrated GPUs or older CPUs (like i3 or i5 laptops with low RAM) may struggle significantly or fail to load the editor entirely. Unreal Engine Advanced Fixes

If you have waited several hours and there is no CPU activity, try these steps: Disable XGE Shader Compilation

: This can sometimes interfere with local loading. Navigate to your engine config directory (usually Epic Games\UE_X.XX\Engine\Config\ConsoleVariables.ini ) and ensure r.XGEShaderCompile = 0 Clear Cache : Locate your project's Intermediate folders and delete them to force a clean re-initialization. Run as Administrator : Ensure the Epic Games Launcher and the Mod Kit have full administrative permissions. Unreal Engine Have you checked your Task Manager yet to see if those ShaderCompileWorker processes are running? [Solved] Unreal Editor loading stuck at 45% - C++ When the Hello Neighbor Mod Kit gets stuck

If your Hello Neighbor Mod Kit is stuck at 45%, the primary fix is simply to wait. This is a common behavior of the Unreal Engine 4 editor when it is compiling shaders for the first time. ⚙️ Why it stops at 45%

Shader Compilation: This is the stage where the engine processes all the lighting and textures.

Initial Launch: The first time you open the kit, it must compile thousands of shaders. Subsequent launches will be much faster.

CPU Intensity: This process uses a large amount of your computer's processing power. You can verify this by checking your Task Manager for "Shader Compile Worker" processes. 🛠️ Troubleshooting Steps

If the kit has been stuck for several hours without progress, try these steps: 1. Just Wait (The "Patience" Fix)

Depending on your computer's speed, this can take anywhere from 10 minutes to over an hour.

Do not close the program unless it is marked as "Not Responding" for a very long period.

Avoid running other heavy programs in the background to speed up the process. 2. Check Hardware Requirements

If you have waited for 3+ hours and nothing has happened, your hardware might be the issue.

Dedicated GPU: Ensure you are not running on integrated graphics. Root Causes

Storage: Move the mod kit to an SSD if possible; it significantly improves loading times. 3. Update Graphics Drivers

Outdated drivers can cause shader compilation to fail or hang. Check your GPU manufacturer's site for the latest version: NVIDIA Drivers AMD Drivers 4. Firewall & Internet Issues

Sometimes the engine hangs while trying to verify files online. Try disconnecting from the internet and launching the kit.

Ensure the Epic Games Launcher and the Mod Kit have permissions through your Windows Firewall. 📂 Advanced Fix: Clearing Cache

If the loading is truly broken, you can try clearing the local save data:

Navigate to your mod kit folder (usually in Epic Games\HelloNeighborModKit). Go to HelloNeighbor > Saved.

Delete the DerivedDataCache folder. This forces the engine to restart the compilation process cleanly. If you'd like to proceed, let me know: What are your PC specs (specifically your CPU and GPU)? How long has it been stuck at 45%? Is this your first time opening the Mod Kit? [PC] The game crashes at start – Hello Neighbor Support

Here’s an informative review of the issue “Hello Neighbor Mod Kit stuck at 45%” — covering what causes it, common fixes, and whether it’s a software or user-side problem.

Root Causes

1. Shader Compilation Stall: The Mod Kit is attempting to compile complex shaders (materials, lighting, fog) and is hanging on a specific asset that is corrupted or too complex for the system to process in one go.
2. Missing Dependencies: The map you are trying to load is referencing an asset from the base game that the Mod Kit cannot find or unpack.
3. System Resource Bottleneck: The system is running out of allocated RAM or VRAM during the asset loading phase.
4. Corrupted Project Files: A specific map file (Level) or Blueprint created by the user has become corrupted.

🚫 What Doesn’t Work (Myths)

• Reinstalling the entire game without clearing local appdata – often keeps the same corruption.
• Changing in-game graphics settings – you can’t reach settings before the 45% stall.
• Running in Windows 7 compatibility mode – no effect.

4. Restart Shader Compilation

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

1. Close the Editor.
2. Navigate to your project folder: [YourProject]/Saved/ShaderDebugInfo.
3. Delete the contents of this folder (do not delete the folder itself, just the files inside).
4. Relaunch the Editor. This forces the engine to re-evaluate the shaders from scratch.
