πŸ“– About This Skill

name: ue-log-analyzer description: | Analyze Unreal Engine log files for errors, warnings, crashes, and performance issues. Use when: (1) User provides UE log file, (2) Analyzing crash dumps, (3) Debugging startup issues, (4) Finding performance bottlenecks in UE projects, (5) Checking pak mounting errors, (6) Lua errors in UnLua

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

    Output Format

    Provide findings in:

  • Error count by severity (Fatal/Error/Warning)
  • Timeline of events
  • Likely root cause
  • Suggested fixes (δΌ˜ε…ˆηΊ§ζŽ’εΊ)
