(using Unity 2022.3.22f1)


![IMG](./img/main.png)

This plugin enables a functionality similar to Blender's decimate feature within Unity.

This plugin supports both `Mesh Filter` and `Skinned Mesh Renderer`. 

It can handle used on any mesh that can be imported into Unity (`.fbx`, `.glTF`, `.dae (Collada)`, `.obj`, `.GLB`, `.asset`, etc.). 

Additionally, even after optimization, BlendShapes, Bones, Bone Weights, and Sub Meshes will be preserved.

decimate functions are created by using **UnityMeshSimplifier**[[1]][UnityMeshSimplifier_github]

### How to use

---

![GIF](./img/showup.gif)

Select an object with a mesh from the Hierarchy or choose it from the ObjectField to use the plugin.

Similar to Blender, adjust the `Decimate Level` and press `Apply Decimation` to execute the decimation.

Clicking `Revert` will restore the original file.

Please note that Revert will not work after clicking on a different object (the original mesh will remain, so you can replace it to restore).
