UE Log Analyzer

Quick Start

Use the nodes tool to read log files from the paired computer, or use read for local files.

Common Error Patterns

Critical Errors (Fatal)

LogInit: Session CrashGUID
Fatal error:
Assertion failed:
Ensure condition failed:

Rendering Issues

LogD3D12RHI: Error:
LogVulkanRHI: Error:
LogRendererCore: Warning:

Lua/UnLua Errors

LogUnLua: Error:
LogUnLua: Warning:
attempt to index a nil value

Pak/Loading Errors

LogPakFile: Error:
LogStreaming: Error:
LogAssetRegistry: Error:

Network Issues

LogNet: Warning:
LogOnline: Error:

Analysis Workflow

1. Find errors: Search for Error:|FATAL|CRASH|Assert
2. Find warnings: Search for Warning:
3. Check crash: Look for Session CrashGUID
4. Lua errors: Search LogUnLua:
5. Timing: Check timestamps for hang points

Project-Specific Patterns

For SilverPalace project:

• HeSDK errors: HeSDKLogError:
• Module loading: MainModule_, SubModule_
• VersionUpdate: MainModule_VersionUpdate
• BigWorld: MainModule_BigWorld

Common Issues & Solutions

1. UMG_GeneralTransitions Missing

LogStreaming: Error: Couldn't find file for package /Game/UI/VX/VX_Common/UMG/UMG_GeneralTransitions
LogUnLua: Error: LoadedAsset is nil

Fix: Check pak packaging includes this UI asset

2. SysStartUpDev nil

Error: c_UMG_Login_Announcement.lua:26: attempt to index a nil value (field 'SysStartUpDev')

Fix: Check Lua config table for SysStartUpDev entry

3. Scalability ini error

Ensure condition failed: false
Scalability.ini can only set ECVF_Scalability console variables
('r.Mobile.AntiAliasing'='2' is ignored)

Fix: Fix Scalability.ini r.Mobile.AntiAliasing value (0 or 1)

4. Shader/PSO errors

LogD3D12RHI: Error: Failed to create pipeline state

Fix: Rebuild shaders or clear shader cache
