Asset Bundler - Unreal Engine 5.7 Editor Plugin

AssetBundler is an Unreal Engine editor plugin that bundles a skeletal mesh with its related assets into a single folder.

It is focused on cleanup and organization of character or weapon asset sets where the skeletal mesh, physics asset, skeleton, materials, and textures are spread across different locations.

Features

• Content Browser context action: Bundle Assets
• Supports selection from:
  • Skeletal Mesh
  • Physics Asset
• Detects and displays:
  • Skeletal Mesh
  • Physics Asset
  • Skeleton
• Shows related assets:
  • used materials
  • used textures from those materials
• Double-click navigation to Content Browser for:
  • skeletal mesh
  • physics asset
  • skeleton
  • materials
  • textures
• Move options:
  • Move Physics Asset default: true
  • Move Skeleton default: false
• Always moves:
  • materials
  • textures
• Never moves:
  • skeletal mesh
• Moves assets into the same folder as the selected skeletal mesh
• Async bundling flow with:
  • confirmation dialog
  • progress display
  • cancel support
• Undo-safe asset moves
• Moved assets are marked dirty

Current Behavior

When bundling starts, AssetBundler builds a move plan using the selected skeletal mesh as the target root.

Move rules:

• skeletal mesh: not moved
• physics asset: moved only if enabled
• skeleton: moved only if enabled
• materials: always moved
• textures used by those materials: always moved

Target folder:

• the folder containing the skeletal mesh

If an asset is already in the target folder, it is skipped.

Usage

1. In the Content Browser, right click a Skeletal Mesh or Physics Asset.
2. Click Bundle Assets.
3. Review detected assets in the Asset Bundler window.
4. Configure:
   • Move Physics Asset
   • Move Skeleton
5. Click Bundle.
6. Confirm the move summary.
7. Wait for bundling to finish or click Cancel while it is running.

UI Overview

The window currently includes:

• preview rows for:
  • skeletal mesh
  • physics asset
  • skeleton
• move options block
• used materials list
• used textures list
• progress bar and status text
• Bundle and Cancel buttons

Asset Detection

Physics asset resolution uses several fallbacks so it can work from either selected asset type:

1. direct skeletal mesh physics asset reference
2. skeletal mesh asset registry tag
3. physics asset lookup by PreviewSkeletalMesh

Undo and Dirty State

Bundle operations are wrapped in an editor transaction.

This means:

• asset moves are undoable
• moved assets are explicitly modified
• moved assets and packages are marked dirty

Installation

As a project plugin

Copy the AssetBundler folder into:

YourProject/Plugins/AssetBundler

Then regenerate project files if needed and open the project in Unreal Editor.

Build requirements

• Unreal Engine 5
• Editor module build

Status

Current state:

• editor-only plugin
• focused on skeletal mesh asset bundling
• intended for internal tooling and workflow acceleration

Limitations

• currently supports only skeletal mesh oriented workflows
• currently opens from:
  • skeletal mesh
  • physics asset
• move logic is limited to:
  • physics asset
  • skeleton
  • materials
  • textures
• no custom destination folder yet
• no preview diff panel yet
• no reference graph visualization yet

Roadmap Ideas

• custom destination folder
• detailed move report
• reference graph preview
• support for animation assets
• filtering which materials or textures should be moved
