MeshKit v4.0 Overview

MeshKit is an integrated system for editing and optimising meshes, along with a unique automatic mesh management system that helps to prevent accidental deletion or modification of meshes when sharing them across scenes ( a common scenario for combining meshes or using prefabs with shared meshes).

MeshKit offers some handy tools to flip meshes, make them double-sided, or to dynamically rebuild them with or without tangents and normals on the fly – all without affecting the original meshes. You can even recreate Light mapping UVs (Editor Only).

MeshKit also excels at combining 3D assets that were not even designed for games, offering a dedicated approach for dealing with Submeshes using powerful separation tools. This streamlines your game, significantly reduces draw calls and reduces overhead!

That’s not all, MeshKit includes a powerful decimator tool which can reduce the triangles of complex meshes as well as an Automatic LOD tool that can dynamically create a decimated LOD Group with a single click! As objects move away from the camera, their lower poly versions will be used which boosts performance!

MeshKit provides its functionality in 3 ways: Editor Tools, Runtime Components and a fully accessible API.


  • Reduce mesh triangles with a powerful Decimator!
  • One-click Auto LOD tool!
  • Separate and combine Meshes.
  • Fully handles combination of meshes over 64k vertices.
  • Set the maximum number of vertices per combined object.
  • Combine Mesh Renderers & SkinnedMeshRenderers with atlasing.
  • Invert meshes.
  • Make meshes double-sided.
  • Strip unneeded vertices and extras from meshes.
  • Dynamically remove or add tangents and normals.
  • Recreate Light mapping UVs (Editor Only).
  • Easy to use Editor Tools.
  • Runtime components.
  • Powerful and easy to use API.
  • Automatic asset management for your processed meshes. Prevent accidental deletion of processed meshes when sharing them between scenes and easily delete unused meshes to free up memory with the “Clean Scene” tool.

Requirements – Unity 2021.3 or higher. (Older versions available compatible with 2019.4)

MeshKit Tutorial Videos

1) MeshKit – Editing Meshes

Find out how to make basic edits to meshes and touch on the basics of MeshKit’s automatic Asset Management.

2) MeshKit – Mesh Optimization

Explore the workflow of efficiently optimizing your scenes. This video concentrates on the “Separate” and “Combine” tools.

3) MeshKit – Runtime Tools

Another powerful way to use MeshKit is at runtime. This is easy with either the API or the powerful and convenient runtime components. This video explores how easy it is to use the runtime components.

4) MeshKit – Automatic Asset Management Explained

MeshKit helps you to organise your new meshes and helps you to avoid any issues with combining meshes. In other tools, if you combine a mesh in one scene and make a change in another, everything breaks. Not in MeshKit! This shows you how MeshKit handles meshes and prefabs to keep you working the “easy” way! 🙂

5) MeshKit – Decimator & Automatic LOD Explained

MeshKit allows you to easily decimate meshes and create levels of detail (LOD) groups with just a few clicks! This is a must-have tool for lowering the number of triangles to be rendered in the scene which can lead to significant performance boosts!

6) MeshKit – Combining & Atlasing Skinned Mesh Renderers

MeshKit v3 now allows you to combine skinned mesh renderers with a few different workflows, including one with texture atlasing! This video explores how these features work and the incredible performance boosts that can be gained!

7) MeshKit – Combining & Atlasing Skinned Mesh Renderers

MeshKit v3.1 not only includes the new “Untile” tool, it also allows you to combine mesh renderers with a few different workflows, including one with texture atlasing! This video explores how these features work and the incredible performance boosts that can be gained!
