MatDelete¶

Quick material removal tool for cleaning up object material assignments

What is it?¶

MatDelete is a simple but powerful utility that removes all materials from selected objects in one operation. Perfect for cleaning up imported models, removing unwanted material assignments, or preparing objects for new material workflows. It handles both object-level materials and resets polygon material indices to prevent conflicts.

Access and Shortcuts¶

Pie Menu: Cleaning/Mirror section → "MatDelete (Clear Materials)"
Operator: damtools.mat_delete
Requirements: One or more objects selected
No modal interface - executes immediately

Workflow¶

Select one or more objects that have materials you want to remove
Activate MatDelete from the pie menu cleaning section
The tool immediately removes all materials from selected objects
A report shows how many materials were removed and objects affected
Objects are now clean and ready for new material assignments

Instant material cleanup with detailed feedback

Parameters¶

Target Objects: - All selected objects with material data - Works with Meshes, Curves, Text objects, and other material-capable types - Processes multiple objects simultaneously

Cleanup Actions: - Removes all material slots from object data - Resets polygon material indices to 0 (for meshes) - Prevents orphaned material references

Tips¶

Use before applying new materials to ensure clean slate
Perfect for imported models with unwanted materials
Works on multiple objects simultaneously for batch processing
Safe operation - only removes material assignments, not the materials themselves
Material data blocks remain in Blender unless orphaned and purged
Particularly useful for 3D printing workflow where materials aren't needed
Great for cleaning up before exporting to formats that don't support materials
