✨ New: Twins Finder

• Find Twins finds every identical copy of the selected mesh, by its shape, never by its name.
• Find All Twins finds every group of identical copies at once, with a progress bar. Press Esc to cancel.
• Link Object Data and Link All Twins make copies share one mesh, so the file gets lighter and editing one copy edits them all.
• Merge Twins and Merge All Twins join copies into one mesh instead.
• Almost identical with a Tolerance slider also catches copies that were exported a little differently.
• Keep twins in place keeps each copy's position and rotation when it is linked, mirrored copies included.
• Target (Scene, Collection or Hierarchy) chooses where to search.
• Color each group gives every group of linked copies its own color.

🧩 New: Parts Finder

• Identify Parts finds the separate parts inside one mesh and gives each its own material, ready for texturing.
• Group identical parts gives identical (and nearly identical) parts one shared material.
• Smart part detection also splits parts that are joined where they touch.
• Welding (Merge by Distance first) joins loose faces from glTF and STEP imports and keeps their shading.

🔧 Merge, improved

• Color each part: every original part keeps its own material after a merge, so you can still select or texture it. Identical parts share one.
• Deepest groups only for Merge by Group merges just the lowest groups and keeps the rest of the hierarchy.
• Merged results now take the exact name of their Empty or collection, without ".001".

🎨 Redesigned panel

• Every action sits in its own box, with its options right under its button.
• New icons, clearer labels, and short hints when a button needs a selection.
• Preferences for the matching tolerances and the confirmation dialogs.
• Delete Unused Empties is now called Delete Childless Empties.

⚡ Fast on big scenes

• Scenes with thousands of objects scan in seconds, and Blender stays responsive while it scans.
