Mirror Master 🪞 automates the tedious, error-prone steps of creating symmetry in Blender. Instead of manually bisecting, setting origins, creating mirror targets, and tuning merge/clip settings, Mirror Master does it reliably in a single click — saving time and preventing common mistakes (like assigning a modifier’s mirror object to its owner). ✅

Perfect for character artists, hard-surface modelers, and anyone who frequently needs precise mirrored geometry.

What it does

• ✂️ Cleanly bisect meshes along X/Y/Z through object origin or 3D Cursor.
• 🗑️ Delete the chosen half automatically (positive/negative).
• 🎯 Set object origin (Geometry / Bounding Box / 3D Cursor) before mirroring.
• 🔁 Add a preconfigured Mirror modifier (axis, clip, merge threshold).
• 🧭 Create a unique, scene-linked Empty and assign it as mirror_object (safe — never assigns the owner object).
• ▶️ Optional one-click Apply for destructive workflows.
• 🛡️ Robust error handling and helpful warnings for edge cases.

Why you’ll love it

• ⚡ Speed up setup — spend more time modeling, less time fiddling.
• 🧰 Safe & reliable — prevents the common “mirror_object” assignment bug.
• 🔄 Non-destructive workflow — tweak with an Empty before applying.
• 📏 Accurate — consistent origin placement reduces mirror artifacts.

Installation (4 steps) 🖱️

1. Download and unzip the package.
2. In Blender: Edit → Preferences → Add-ons → Install… and select mirror_master.py.
3. Enable Mirror Master in Add-ons.
4. Open View3D → Sidebar (N) → Mirror Master and use Cut + Mirror or Add Mirror Only.

Recommended workflows ✨

Quick symmetry

1. Select mesh → Axis = X → Cut Through = Origin → Delete Side = POS → Cut + Mirror. ⚡

Non-destructive exploration

1. Use Empty Mirror Object → transform Empty to offset/rotate the mirrored half → apply when satisfied. 🎛️

Precise plane

1. Move 3D cursor to exact plane → Cut Through = 3D Cursor → Cut + Mirror. 🎯

FAQ ❓

Q: Which Blender versions are supported?
A: Blender 2.8+ (validated on Blender 3.x). If you hit a version issue, message me and I’ll patch it. 🛠️

Q: I get warnings about bisect or loose verts.
A: Try toggling use_fill in the bisect call (advanced) or increase Merge Distance slightly (0.001 → 0.01). Full troubleshooting in README. 🔧

Q: Can I reuse the same Empty instead of creating many?
A: Planned for v1.2 — for now Mirror Master creates uniquely named empties to avoid conflicts. ♻️

Q: Is this free for commercial projects?
A: See LICENSE.txt included. Typical options: Personal Use (free) / Commercial (paid). Contact me for enterprise licensing. 💼
