Polytool is a Unity package that helps you with optimizing your models, right inside Unity!
It makes optimizing models quite simple for those who value a quick and easy solution. You can just choose a preset and go!
It was originally created to optimize VRChat avatars but works for many different optimization jobs inside Unity.

Avatars used in the demos are the Leggy, Rex, and Nardo.
Features
Automatic mesh decimation/simplification (Using a highly custom version of UnityMeshSimplifier)
Merging both skinned and static meshes into a single mesh (automatic weight painting for static meshes, too!)
Material merging with automatic texture atlassing
Automatic bone reduction and merging
Preserves armatures, blendshapes, animations, UVs, and weight painting
Built-in optimization presets for specific use cases like VRChat Quest avatars
Preset editor to make and save your own optimization presets
Limitations
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 avatar that exists and 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 into infinity.
Polytool exists as 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 very skilled at things like mesh and material optimization, maybe Polytool isn't the best solution for you.
Getting Started
Requirements
Unity Editor (Tested with 2019.4.31f1)
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 by right-clicking an object in your Unity scene and choosing "Polytool".
You can play around with the various presets and settings without having to worry too much 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!
