Mesh Editor Tool for Unity – Professional 3D Modelling tool

Mesh Editor Tool for Unity—Professional 3D Modelling & Scene Setup, All Inside the Editor

Transform the way you work with meshes in Unity! The Mesh Editor Tool is an all-in-one editor extension that brings Maya/Blender-style mesh editing, UV operations, mesh combination & separation, face/pivot management, LOD generation, mesh optimization, and beautiful HDRI scene setup directly inside your Unity Editor, with NO runtime overhead.

Key Features

• Mesh Editing Toolbox: Reverse faces, double-sided mesh generation, harden/soften edges, tri-to-quad conversion, and weld vertices—all in one click.
• Full Modelling Workflow: Switch between Object and Face selection modes. Select, move, rotate, scale, and delete individual faces directly in Scene view with Unity's familiar transform tools.
• Non-Destructive Workflow: All mesh changes are undoable, and you can selectively delete or keep originals when combining or separating meshes.
• Combine & Separate: Seamlessly merge multiple GameObjects (with materials preserved) or split meshes by material and by loose parts.
• Pivot Editing: Instantly reset mesh pivot to center, or assign it to any other object in the scene for perfect alignment.
• Mesh Optimization & LOD: One-click mesh simplification with visual quality slider, plus rapid LOD level creation for performant scenes.
• Smart Poly Count HUD: See real-time vertex and triangle counts for any selection in Scene view, or audit your whole scene at a glance.
• HDRI Scene Setup: Drag and drop HDRI images, tweak exposure/rotation, and set a beautiful skybox for polished lighting—no scripting required.
• Safety & Reliability: SceneView overlays keep you informed, mesh colliders auto-update for selection fidelity, and all actions are integrated with Unity Undo.
• Zero Coding Required: No need to touch C# or build custom scripts. Just install and start editing immediately from Tools > Mesh Editor.

Usage:

1. Place the script in any Assets/Editor/ folder.
2. Open via Tools > Mesh Editor.
3. Select objects and unlock pro-level mesh operations—combine, separate, UV, optimize, and more.

Perfect for game devs, level artists, and anyone who needs to tweak 3D meshes or polish scenes quickly—no round-tripping to external DCC tools.

Upgrade Unity’s hierarchy-based workflow with features you wish were built in.

Requirements: Unity Editor 2019.4+.
