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.
