STOP GUESSING. START DIAGNOSING.

4 PROFESSIONAL UNREAL ENGINE EDITOR PLUGINS – ONE COMPLETE DIAGNOSTIC TOOLKIT.

Find problems faster. Understand their causes. Fix them with confidence.

This bundle combines four powerful Unreal Engine diagnostic plugins to help you identify Blueprint errors, hidden memory dependencies, multiplayer replication issues and performance bottlenecks.

Four common problems. Four specialized solutions.

• Blueprint won't compile? → Blueprint Health Doctor
• Unexpected memory usage? → Blueprint Reference Doctor
• Multiplayer not replicating? → Replication Doctor
• Unexplained FPS drops? → Level Performance Doctor

Every included plugin is the same full product as its individual Fab listing, including updates, documentation and support.

WHAT'S INCLUDED

1. BLUEPRINT HEALTH DOCTOR

Find broken Blueprints before they break your build.

Stop opening and compiling Blueprints one by one.

Blueprint Health Doctor automatically scans and compiles Blueprints in dependency-aware order, helping you discover errors before they become larger development problems.

Key Features

• Automatically compile Blueprints across selected scopes
• Dependency-aware compilation order
• Detect and categorize errors and warnings
• See original Unreal compiler messages
• Identify affected Blueprints and nodes
• Jump directly to problematic nodes
• Receive practical diagnostic guidance
• Run scans in a separate Unreal Editor process
• Protect your active editor session from scan-related crashes

100% diagnostic – your assets are never modified.

2. BLUEPRINT REFERENCE DOCTOR

Discover hidden dependencies and unnecessary memory costs.

A single hard reference can pull an entire chain of assets into memory.

Blueprint Reference Doctor reveals what your Blueprints reference, why those dependencies exist and where unnecessary loading may occur.

Key Features

• Rank assets by total load footprint
• Analyze hard-reference dependency chains
• Identify the exact property or pin causing references
• Detect circular references
• Find broken references and redirectors
• Asset Registry audits without loading assets
• Deep Analysis for Blueprint graphs and variables
• Preview hard-to-soft reference conversions
• Dry-run workflow before modifying assets

Understand your project's loading behavior and identify opportunities to reduce dependency costs.

3. REPLICATION DOCTOR

Find out why your multiplayer systems aren't replicating.

Stop searching through networking logs and guessing why actors, variables or RPCs behave incorrectly.

Replication Doctor combines static networking diagnostics with live multiplayer monitoring.

Static Replication Audit

Detect configuration problems before pressing Play:

• Replicated variables on non-replicating actors
• Missing RepNotify functions
• RPCs without valid network callspace
• Server RPCs inside Level Blueprints
• Multicasts on non-replicating actors
• Additional replication configuration problems

Live Multiplayer Diagnostics

• Compare server and clients side by side
• Inspect actor replication with the Live Actor Matrix
• Identify which replication gate blocks an actor
• Monitor sent, delivered, queued and dropped RPCs
• Preview supported class-default fixes
• Revert supported changes when needed

See where replication fails – and understand why.

4. LEVEL PERFORMANCE DOCTOR

Find exactly where your level loses performance.

No more manually walking through maps while watching performance statistics.

Choose your map, define your target frame rate and press Start.

Level Performance Doctor automatically analyzes locations throughout your level using a separate Unreal Editor instance.

Real Performance Measurements

• Frame Time
• Game Thread Time
• Render Thread Time
• GPU Time
• Location-based performance measurements
• Performance hotspots

Visual Performance Analysis

• Interactive performance heatmap
• Performance scores from 0–100
• Transparent scoring formula and weights
• Evidence-backed performance findings
• Identification of likely performance contributors

No manual camera placement. No console commands. No walking the entire level.

Find performance problems using real measurements instead of guesswork.

BUILD WITH MORE CONFIDENCE

Each plugin works independently, but together they provide a broader diagnostic workflow for Unreal Engine development.

WHY CHOOSE THIS BUNDLE?

FIND PROBLEMS EARLIER

Discover compilation, dependency and networking configuration issues before they become harder to diagnose.

SAVE DEVELOPMENT TIME

Replace repetitive manual investigations with dedicated diagnostic tools.

UNDERSTAND THE ROOT CAUSE

Get detailed findings, visualizations and technical evidence instead of unexplained warnings.

DIAGNOSE SAFELY

Blueprint Health Doctor performs read-only diagnostics, while supported corrective workflows in other tools provide previews or reversible changes.

KEEP YOUR WORKFLOW INSIDE UNREAL

Work directly with dedicated Unreal Engine editor tools. Intensive scans can use separate editor processes where supported.
