Auto File Cleaner - Remove Unused Materials, Images & Meshes | Blender 4.0–5.0+
NovaStrikes
v3.1.1 — Bug Fixes & Stability
-
Fixed: Merging duplicate materials/images now actually removes the leftover duplicate. Previously, it looked like Merge didn't work, and the same group kept reappearing after a rescan.
-
Improved: Duplicate detection is now much more accurate — materials with the same node count but different colors/setups are no longer falsely flagged as duplicates, and generated/blank images no longer get grouped incorrectly. (Still recommend reviewing a duplicate group before merging — detection is safer now, not 100% foolproof.)
-
Fixed: Linked library materials/images are now fully excluded from duplicate scanning, preventing errors when trying to merge them.
-
Fixed: Backup restore was broken for most users — it now reliably finds and restores the correct backup file instead of guessing based on timestamps.
-
Fixed: Manual backups (via the Backup Now button) can now be restored — previously only automatic backups were restorable.
-
Fixed: Reported "freed space" after cleanup is now much more accurate for meshes and images, instead of showing near-zero values.
-
Improved: Panel UI no longer causes viewport stutter on projects with a large cleanup history.
- Added missing LICENSE.txt for extension compliance.
v3.1 — What's New
- Merge & Remap Duplicates — new "Merge" button on flagged duplicate groups. Instead of just showing you the dupes, Auto File Cleaner now remaps every user of the duplicate materials/images onto one kept copy, then Purge can clean up the leftovers. Gated by Safe Mode + auto-backup, same as every destructive action.
- Restore Last Backup — one-click restore of your most recent automatic backup, right from the panel. No more digging through folders after a cleanup you regret.
- Per-Category Freed-Space Breakdown — after a Delete/Purge/Quick Clean, see exactly where space was freed (e.g., Images: 180MB, Materials: 12MB) instead of one lump number.
- Missing Textures Detector — new scan flags external image files whose file path no longer resolves on disk, so broken links get caught before they turn into a "why is this pink" render surprise.
- License headers standardized across all files; links added (Portfolio, Superhive, GitHub).
