Clean duplicated materials and image textures in Blender

Aeris Material Toolkit is a practical Blender add-on for artists who often work with imported assets, kitbash files, game models, outsourced scenes, or production files that contain duplicated materials and image textures.

When importing multiple meshes, Blender scenes can quickly become messy with duplicated datablocks such as Material.001, Material.002, Image.001, and Image.002. This tool helps you detect, replace, and clean those duplicates faster, so your file stays lighter, cleaner, and easier to manage.

What this add-on helps with

• Find duplicate materials grouped by base name
• Find duplicate image textures grouped by base name
• Replace duplicated materials with the correct material datablock
• Replace duplicated image textures inside material node trees
• Select meshes using a specific material or image texture
• Quick cleanup for numeric suffix duplicates such as .001, .002, .003
• Break image paths for texture relinking workflows
• Run Find Missing Files from a chosen texture folder
• Relink images by matching base file names
• Purge unused datablocks after cleanup
• Batch apply material render method for alpha/foliage workflows
• Batch apply image alpha mode
• Batch apply image color space

Designed for production cleanup

This tool is especially useful when working with assets that were imported from other DCC tools, downloaded from asset libraries, merged from multiple Blender files, or prepared for game production workflows.

Instead of manually checking every material slot and image texture node, you can refresh the duplicate list, inspect each group, select affected meshes, and replace duplicates directly from the N-panel.

Typical use cases

• Cleaning imported FBX or OBJ assets
• Fixing duplicated materials after appending/linking assets
• Cleaning duplicated image textures after importing multiple meshes
• Preparing cleaner Blender files for game asset workflows
• Managing foliage or alpha texture settings faster
• Relinking missing textures from a new texture folder
