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
: 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? hello neighbor mod kit stuck at 45
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.
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
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. This bypasses permission issues and potential sector errors
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.

Hello Neighbor Mod Kit Stuck at 45%: Causes and Solutions Getting stuck at 45% while loading the Hello Neighbor Mod Kit is one of the most common issues developers face when using the Unreal Engine-based toolkit. This specific percentage is the "gatekeeper" moment where the editor transitions from loading core files to compiling complex assets. Why Does It Freeze at Exactly 45%?
In the Unreal Engine architecture (which powers the Mod Kit), 45% is the specific stage where the editor begins compiling shaders and initializing global project settings.
Shader Compilation: Shaders are scripts that tell the GPU how to draw the world. The first time you launch the kit, thousands of these must be translated into a language your graphics card understands.
Deferred Initialization: The engine may appear frozen because it is using 100% of your CPU to process these files in the background without updating the loading bar. Solution 1: The "Patience" Method (Highly Recommended)
In most cases, the Mod Kit is not actually crashed; it is just working extremely hard. Check Task Manager: Press Ctrl + Shift + Esc.
Verify Activity: If "HelloNeighbor" or "UE4 Editor" is using high CPU (often 90–100%), it is still working.
Wait: Depending on your processor speed, this can take anywhere from 15 minutes to over an hour on the first launch.
Do Not Click: Interacting with the window while it is loading can cause Windows to report it as "Not Responding," which may lead you to force-quit a healthy process. Solution 2: Clear the Derived Data Cache (DDC)
If you have waited for several hours and the kit is still stuck, your shader cache might be corrupted.
Locate the Folder: Navigate to your Mod Kit installation directory or your local AppData folder (%LOCALAPPDATA%\UnrealEngine).
Delete the Cache: Find the folder named DerivedDataCache and delete it.
Relaunch: The editor will re-create these files. Note that it will still sit at 45% during the new compilation, but this time it should eventually pass. Solution 3: Firewall and Admin Permissions
Security software can sometimes block the sub-processes (like the Shader Compile Worker) required to finish loading.
Disable Firewall: Briefly turn off your Windows Firewall to see if the loading bar advances. By following this comprehensive guide, you should be
Run without Admin: Ironically, running as an Administrator can sometimes prevent the "ShaderCompiler" from launching correctly because only the main engine has elevated rights. Try launching the .exe normally. Solution 4: Hardware and Driver Checks
The Hello Neighbor Mod Kit (based on UE 4.19) is resource-intensive.
Update GPU Drivers: Ensure you have the latest drivers from NVIDIA or AMD.
Minimum Specs: Laptops without a dedicated GPU or systems with less than 8GB of RAM may never successfully pass the 45% mark due to memory exhaustion. Troubleshooting Summary Table Why it works Expected Time Just Wait Allows CPU to finish Shader Compilation 15 - 60+ mins Check Task Manager Confirms the app is still calculating, not frozen Delete DDC Forces a clean re-compile of all assets Check Firewall Ensures background worker tasks aren't blocked

Here’s an informative post regarding the issue of the Hello Neighbor Mod Kit getting stuck at 45% loading.
Title: Troubleshooting Guide: Hello Neighbor Mod Kit Stuck at 45% Loading
Body:
If you’re a modder or map creator for Hello Neighbor, you’ve likely encountered the frustrating issue where the Mod Kit gets stuck at exactly 45% during loading. This is a known pain point in the community, but fortunately, it’s often fixable. Below is a breakdown of why this happens and the most effective solutions.
If deleting the cache didn't work, a core game file might be missing or broken.
Right-click the .exe → Properties → Compatibility → Check Run as admin and Disable fullscreen optimizations.
Users attempting to install the Mod Kit observe the progress bar reaching precisely 45%. At this point, the download speed typically drops to 0.00 MB/s, or the launcher enters a "Preparing" loop before eventually failing with an error message or remaining stuck indefinitely.
Technical Context: The Hello Neighbor Mod Kit is built on Unreal Engine 4. Unlike standard game installations, the Mod Kit includes large binary files and engine prerequisites. The 45% mark usually coincides with the transition from downloading core assets to downloading engine-specific binaries or verifying the massive main asset file.
If nothing works, uninstall the Mod Kit completely.
