Reduce Mesh Triangles Within Unity

使用 Unity Mesh Simplifier 在 Unity 编辑器内降低模型面数
不需要使用 Max 或者 Blender Decimate 3D 软件
减面之后，再使用 FBX Exporter 导出减面的 FBX 就可以了

写了个编辑器脚本调用 mesh simplier api 方便使用

using UnityEditor;
using UnityEngine;
using UnityMeshSimplifier;

public class MeshSimplifyTool 
{
    [MenuItem ("GameObject/Simplify Mesh", false, 30)]
    static void OnContextItem (MenuCommand command)
    {
        if (Selection.objects.Length <= 0) 
        {
            DisplayNoSelectionDialog ();
            return;
        }
        SimplifyMesh ();
    }

    private static void SimplifyMesh()
    {
        var selectedGOs = Selection.GetFiltered<GameObject> (SelectionMode.TopLevel);
        if (selectedGOs.Length > 0)
        {
            var go = selectedGOs[0];
            var mf = go.GetComponent<MeshFilter>();
            if (mf == null)
            {
                DisplayNoMeshDialog();
                return;
            }

            var mesh = mf.sharedMesh;
            var ms = new MeshSimplifier();
            ms.Initialize(mesh);
            ms.SimplifyMesh(0.5f);
            var destMesh = ms.ToMesh();
            mf.sharedMesh = destMesh;
        }
        else
        {
            DisplayNoSelectionDialog();
        }
    }
    
    private static void DisplayNoSelectionDialog()
    {
        EditorUtility.DisplayDialog (
            "Mesh Simplify Warning", 
            "No GameObjects selected.", 
            "Ok");
    }
    
    private static void DisplayNoMeshDialog()
    {
        EditorUtility.DisplayDialog (
            "Mesh Simplify Warning", 
            "GameObject has no mesh attach.", 
            "Ok");
    }
}

使用步骤

  1. 在 Hierarchy 选中 GameObject 右键点击 Simplify Mesh
  2. 每次减面 50%，可反复点击
  3. 右键选中 使用 FBX Exporter 导出
