MeshPilot – Mesh Workflow Toolkit

**MeshPilot** is an all-in-one mesh editing toolkit for the Unity Editor. Split, merge, fix pivots, repair normals and fill holes on any mesh without leaving Unity or opening a 3D modeling app.

Perfect for level designers, environment artists and developers who work with asset packs, kitbash models or imported FBX files and need quick mesh fixes.

**SPLIT MESHES**

• Paint faces directly in the Scene View and split one mesh into multiple objects
• Multiple named, color-coded groups in a single pass (keys 1-9 switch groups)
• Face, Linked, Angle and Material selection modes
• Angle mode selects a whole flat or smooth surface in one click (e.g. a car hood)
• Box selection with Ctrl + Drag, visible faces only or through the mesh
• Grow, Shrink and Invert the active group
• Auto grouping by Loose Parts or by Material in one click
• Re-edit Split: reopen any split later with its saved groups and adjust it
• Optional Box, Mesh or Convex Mesh colliders for every part
• Save the split result as a Prefab automatically

**MERGE MESHES**

• Combine multiple meshes into one to reduce draw calls
• Pivot options: Center, Bottom Center or First Object
• One mesh per material option and lightmap UV generation
• Skinned Mesh Renderers keep bones, weights and blend shapes
• Save the merged result as a Prefab automatically

**PIVOT TOOL**

• Move the pivot without moving the mesh
• Snap to vertices, faces or presets (Center, Bottom Center, Top, Corners)
• Quick Pivot: fix the pivot of many objects at once

**MESH TOOLS**

• Flip Normals: fix inverted or invisible meshes instantly
• Recalculate Normals with an adjustable smoothing angle (flat to fully smooth)
• Weld Vertices: merge overlapping vertices while keeping UV seams and hard edges
• Remove Unused Vertices to clean up imported meshes
• Works on multiple objects at once and on Skinned Meshes (bones, weights and blend shapes are kept)

**FILL HOLES**

• Automatically detect and cap open holes in a mesh
• Manual mode: fill any area by picking points
• Choose material slot and UV region with a visual UV picker

**EXPORT OBJ**

• Export one or many meshes to .obj with a .mtl material file
• Available from the window, the Tools menu and the Hierarchy context menu
• Skinned meshes are exported in their current pose

**WORKFLOW**

• Full Undo / Redo support
• Original and imported meshes are never modified, MeshPilot always writes new assets
• Works with models imported with Read/Write disabled
• Clean, modern editor window
• Cleanup Tool removes unused generated mesh assets
• Configurable output folder
• Demo scene and full HTML documentation included

**Editor-only: MeshPilot** adds nothing to your builds. Generated meshes are regular assets that work on every platform.
