Material Cleaner Pro is a professional Blender addon designed to simplify material management and keep your scenes clean, organized and optimized.

Why Material Cleaner Pro?
Managing materials manually can quickly become slow and error-prone, especially in large Blender projects.
Material Cleaner Pro automates the most common cleanup tasks while keeping you in full control of every operation. The addon is designed with safety in mind and includes confirmation dialogs, preview tools and Blender Undo support for destructive operations.
Spend less time cleaning your scenes and more time creating.

Features
✅ Remove Unused Materials
Remove materials that are no longer assigned to any object while preserving important data such as Fake User materials and linked assets.
✅ Merge Duplicate Materials
Automatically merge Blender duplicate materials created with numeric suffixes such as:
Material
Material.001
Material.002
Material.003
Only Blender-style duplicate names are processed, preventing accidental merging of intentionally different materials.
✅ Smart Duplicate Detection
Before merging, the addon compares material properties and node trees to ensure that only matching materials are combined.
✅ Remove Empty Material Slots
Delete unused material slots from selected objects with a single click.
✅ Organize Materials
Keep the material list clean, readable and easier to manage in large production scenes.
✅ Safe Preview
Preview duplicate materials before merging them.
✅ Confirmation Dialogs
Every destructive operation requires confirmation before any changes are made.
✅ Blender Undo Support
All cleanup operations fully support Blender's Undo system, allowing you to safely revert changes at any time.
✅ Production Ready
Designed for both small personal projects and professional production environments.
