UE5 Asset Validator Plugin

Status: Scaffolded and under active development. Compilation and live demo in progress on a dedicated UE5 machine.

A custom Unreal Engine 5 editor plugin written in C++ that adds a dockable Slate UI panel for automated asset validation against studio content pipeline standards — with one-click auto-remediation.

Built using the UE5 Asset Registry API, Slate/SlateCore, AssetTools, and the UnrealEd framework. Designed for integration into professional game development pipelines where content quality gates are enforced before check-in.

Key skills demonstrated: UE5 C++ plugin development · Slate UI · Asset Registry querying · Content pipeline tooling · Editor framework integration · Automated asset review · Pipeline standards enforcement

Features

Rule	What it checks	Auto-Fix
Naming Convention	Enforces T_, SM_, SK_, M_, MI_, BP_, A_, PS_ prefixes	✅ Renames via AssetTools
Texture Size Budget	Power-of-two dimensions; per-group max sizes (World 2048, Character 4096, UI 1024)	❌ Manual
LOD Requirements	Minimum LOD levels based on triangle count at LOD0 (10K → 3 LODs, 50K → 4 LODs)	❌ Manual

How to Build

1. Copy this folder into your UE5 project's Plugins/ directory.
2. Right-click your .uproject → Generate Visual Studio project files.
3. Build the [ProjectName]Editor target in Visual Studio or Rider.
4. Enable the plugin in Edit → Plugins → Pipeline Tools.

---

Usage

• Window → Asset Validator — opens the dockable panel
• Select assets in the Content Browser → Validate Selected
• Select a folder → Validate Folder
• Click Auto-Fix All to apply all fixable findings (naming renames)

---

Extending

Add a new rule by:

1. Creating Public/Rules/MyRule.h — implement IAssetValidationRule
2. Creating Private/Rules/MyRule.cpp — implement Validate() and optionally AutoFix()
3. Registering an instance in SAssetValidatorPanel::Construct()

---

Configuration

Edit Config/AssetValidatorRules.ini to change naming prefixes, texture budgets, and LOD thresholds without recompiling.

---

Use Cases

• Content pipeline enforcement at studios using Unreal Engine 5
• Pre-commit asset review before Perforce check-in or Git LFS push
• Automated QA for texture budgets, mesh complexity, and naming standards
• Onboarding new artists to studio asset conventions with immediate feedback
