Remove Duplicate Materials

Remove Duplicate Materials — Blender Add-on

Streamline your Blender projects by easily identifying and removing duplicate materials! This powerful yet user-friendly add-on scans your scene to find materials with identical node setups even if they have different names—and helps you consolidate them efficiently.

Key Features

• Accurate Duplicate Detection: Groups materials by both base name and a deep hash of their node structures and textures, ensuring duplicates are reliably identified beyond simple name matching.
• Preview Support: See material previews directly in the panel for quick identification.
• Flexible Replacement: Replace duplicates within each group by selecting a dominant material or even specifying a completely different replacement material.
• Batch Operations: Replace and clean duplicates one group at a time or all at once for maximum efficiency.
• Material Renaming: Rename the chosen material after replacement to keep your project organized.
• Isolate Meshes: Quickly isolate all meshes using a specific material for easier editing and verification.
• Progress Tracking: Visual feedback during the scanning process keeps you informed.

How It Works

1. Scan your scene to collect and group duplicate materials.
2. Review grouped duplicates with previews and detailed options.
3. Select the dominant material to keep or specify another replacement.
4. Replace duplicates seamlessly across objects and clean up unused materials.
5. Optionally rename materials and isolate meshes for further workflow clarity.

Installation & Usage

Install as a Blender add-on, then access the Remove Duplicates panel in the 3D Viewport sidebar. Click Collect Duplicate Materials to start, then manage each group or clean all duplicates at once.
