UniMerger - Unreal Engine Harmonizer

The Ultimate Mod Processing Tool for Oblivion Remastered

⚠️ WARNING: In-game testing is still pending ⚠️

While comprehensive testing hasn't been completed yet, the conflict detection and analysis features alone make this tool valuable enough to share with the community.

UniMerger is a comprehensive tool that processes and merges mod data for Oblivion Remastered, converting traditional Bethesda modding formats into UE5. 3-compatible PAK files. It bridges the gap between classic .esp/.esm modding and Unreal Engine's modern asset system.

If this tool works as intended, it should replace the need for MagicLoader, TesSyncMapInjector, and NL-Tag Remover by providing a more robust approach than runtime memory injection. Instead of patching the game at runtime, UniMerger pre-processes all mod data into native UE5. 3 formats for seamless integration.

Key Features

• []String Table Processing: Converts mod text (names, descriptions, book content, dialog responses, quest logs) into localized string tables

  []Asset Mapping: Processes FormID-to-asset path mappings for seamless mesh integration

  []Cell Mapping: Handles cell-to-map path assignments for custom locations

  []PAK Conflict Analysis: Advanced hierarchical tree visualization of asset conflicts before installation

  []Custom Search Paths: Configure additional directories to search for mod data

  []ModOrganizer2 Integration: Full compatibility with MO2 virtual filesystem

  []Configuration-Driven: Unlimited string table types through JSON configuration

  []Batch Processing: Handles multiple mods simultaneously with intelligent merging

  How It Works

  1. UniPatcher (xEdit script) processes .esp/.esm files into unified CSV format with localization keys, asset mappings, and geolocation data

  2. UniMerger loads the CSV generated by UniPatcher, then the JSON designed for MagicLoader and lastly the INI designed for UE4SS TesSyncMapInjector. It can find the configuration files in multiple search paths, merging content with score-based deduplication

  3. Template Extraction: Original UAsset templates are extracted using retoc from the game's PAK files

  4. Binary Injection: UAssetAPI loads the templates and surgically injects mod data into the binary structures

  5. PAK Creation: Modified UAssets are packaged back into UE5. 3-compatible PAK files using retoc for distribution

  Supported Data Types
