Polytool For Unity

304 ratings

Polytool is a Unity plugin that helps you optimize your models inside Unity!

It makes optimizing models simple for those who value a quick and easy solution. Choose a preset and go!

It was created to optimize VRChat avatars. It also works for other optimization tasks inside Unity.

The avatars used in the demos are the Leggy, Rexouium, Canis, and Nardo.


  • Automatic mesh decimation/simplification (Using a highly custom version of UnityMeshSimplifier)
  • Merging skinned and static meshes into a single mesh (automatic skinning for static meshes, too!)
  • Material merging with automatic texture atlassing
  • Automatic bone reduction and merging
  • Preserves armatures, blendshapes, animations, UVs, and skinning
  • Built-in optimization presets for specific use cases like VRChat Quest avatars
  • Preset editor to make and save custom optimization presets


  • As with any automated system, your results may vary depending on your situation. You might have to play with the settings of the different functions and be mindful of how many meshes and materials you include to hit your desired level of quality. I can recommend playing around with the trial version to see if you can get a result you are happy with.
  • I can't test every possible avatar, so you may run into a situation that doesn't work as expected. Please report these and I'll do my best to look into it!
  • When decimating, depending on your mesh, you may have to adjust the Denominator Precision slider if you are experiencing mesh errors like triangles flying off.
  • Polytool is a solution for people who value convenience and ease of use or don't have the technical skills to spend hours in Blender and Unity to implement specific performance requirements. If you are already very skilled at things like mesh and material optimization, maybe Polytool isn't the best solution for you.

Getting Started 

To get started, import the Polytool package into your Unity project.

To open the interface, you can access the "Polytool" tab at the top of Unity or right-clicking an object in your Unity scene and choose "Polytool".

You can play around with the various presets and settings without worrying about your original assets. Polytool always makes copies of whatever it touches.

Some operations can take a while, so it's important to be patient with Unity and let it do its thing while it figures everything out!


At this time I am only offering a personal use license.

This means you can use Polytool to create and manage your personal avatars and assets. You cannot take (free or paid) commissions using this package or include any of Polytool's generated assets in any packages (free or paid) that you distribute.

You can upload avatars generated by Polytool as public avatars onto the VRChat platform, as long as they are intended for public sharing.

A commercial license is not available right now. But if you have any questions about acceptable use, contact me.


If you are experiencing any problems or have trouble getting something to work, feel free to reach out to me and I will try to get back to you as soon as possible.
