Hello Neighbor: Mod Kit Stuck At 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 hello neighbor mod kit stuck at 45

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 When the Hello Neighbor Mod Kit gets stuck

: 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 —

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. Step 3: Increase System Resources


Step 3: Increase System Resources

  1. Close any unnecessary programs or background applications.
  2. Consider upgrading your system's RAM or CPU if you're running low on resources.

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.

Why 45%?

The 45% loading mark typically corresponds to the Mod Kit verifying and importing assets (textures, models, audio, and scripts) into the project. When it stalls here, it usually means the kit has encountered something it can’t process—corrupted data, a missing dependency, or an asset that violates the kit’s strict formatting rules.
