Easy AssetBundle Builder

Easy AssetBundle Builder is a powerful custom Editor tool for Unity that streamlines the process of creating, organizing, analyzing, and building AssetBundles. It replaces Unity’s default manual workflow with a visual, data-driven system designed for professional production pipelines.

Unlike the default workflow, which relies on heavy manual configuration and inspector tags, this tool provides full visibility and control through a dedicated interface.Key

Benefits

• Visual Group-Based Management: Organize assets in logical tabs.
• Per-Asset & Per-Group Control: Fine-tune build settings for individual items or entire groups.
• Built-in Versioning: Simple but powerful version tagging for assets and groups.
• Deep Dependency Analysis: Automatically map and inspect asset dependencies.
• Duplicate Detection: Instantly identify and resolve assets duplicated across multiple bundles.
• Comprehensive Metrics: Track build time, total size, and per-bundle sizes for every platform.
• Multi-Platform Targeting: Build for all target platforms from a single window.
• Multiple Compression Modes: Choose from various compression algorithms.

Features in Detail

1. Group-Based Workflow

Manage assets in a flexible, tab-based system.

• Create multiple groups with separate tabs.
• Automatic tab wrapping for an uncluttered UI.
• Independent sorting options per group.
• Assign a unique version number to an entire group.

2. Individual Asset Control

Maintain precise control over every asset in the list. Each asset supports:

• A custom, override label.
• A custom, override version number.
• Automatic detection of duplicate bundle names with an "Auto-Fix" option.
• The ability to be skipped or ignored during the build process.

3. Versioning System

Implement a clear versioning strategy (e.g., Player_v3).

• The version suffix can be toggled globally to be applied or ignored during the build.

4. Sorting Modes

Quickly reorganize your view with multiple sorting modes.

• Individual Asset Sorting:
• None (Manual Drag & Drop)
• Name (Ascending / Descending)
• Type
• Date Added (Newest / Oldest First)
• Dependency View Sorting:
• Name (Ascending / Descending)
• Size (Largest / Smallest First)
• Type

5. Build Metrics

After every build, the tool provides instant, actionable data:

• Total build time (in seconds).
• Overall build size.
• A detailed breakdown of individual bundle sizes.
• Persistent per-platform size tracking for historical comparison.

6. Dependency Analyzer

Gain full visibility into what makes up your bundles.

• Utilizes AssetDatabase.GetDependencies(assetPath, true) to map all dependencies.
• Displays a clear list of every dependent asset and its file size.
• "Click-to-Ping" functionality to instantly locate any asset in the Project view.

7. Duplicate Detection System

Prevent asset bloat by identifying dependencies shared across multiple groups.

• The system builds a dictionary: Dependency → Group → Asset List.
• Dependencies used in multiple groups are flagged with a color-coded severity scale:
• Yellow: Used in 2 groups.
• Orange: Used in 3+ groups.
• Red: Indicates a high-impact, heavy duplication.

8. Output Folder Management

Streamlined management of your build destination.

• Automatically create the target output folder if it doesn't exist.
• Safely clear the output folder before a new build.
• Automatically refresh the AssetDatabase after a build.
• Auto-select the newly built bundle in the Project view for quick access.

9. Drag & Drop System

A fast and intuitive way to populate your groups.

• Supports dragging and dropping single assets.
• Supports dragging and dropping entire folders.
• Performs recursive asset discovery on dropped folders.
• Automatic filtering to ensure only valid asset types are added.

10. Undo Support

Work with confidence, knowing every action is reversible.

• Uses Undo.RecordObject(...).
• Fully integrated with Unity's native Undo system (Ctrl+Z / Cmd+Z).
