MeshInfo

Author: Jonathan Czeck (aarku)

Description

This script will show statistics of the meshes in the current selection. If a parent object is selected, the script will show statistics of the parent's entire hierarchy.

Usage

Place this script in YourProject/Assets/Editor and a menu item will automatically appear in the Custom menu after it is compiled. Then select any number of objects and select the menu item to see triangle and vertex info.

C# - MeshInfo.cs

<csharp>using UnityEngine; using UnityEditor; using System.Collections;

public class MeshInfo : ScriptableObject {

   [MenuItem ("Custom/Show Mesh Info %i")]
   public static void ShowCount()
   {
       int triangles = 0;
       int vertices = 0;
       int meshCount = 0;
       
       foreach (GameObject go in Selection.GetFiltered(typeof(GameObject), SelectionMode.TopLevel))
       {
           Component[] meshes = go.GetComponentsInChildren(typeof(MeshFilter));

           foreach (MeshFilter mesh in meshes)
           {
               if (mesh.sharedMesh)
               {
                   vertices += mesh.sharedMesh.vertexCount;
                   triangles += mesh.sharedMesh.triangles.Length / 3;
                   meshCount++;
               }
           }
       }

       EditorUtility.DisplayDialog("Vertex and Triangle Count", vertices
           + " vertices in selection.  " + triangles + " triangles in selection.  "
           + meshCount + " meshes in selection.  Average of " + vertices / meshCount
           + " vertices and " + triangles / meshCount + " triangles per mesh.", "OK", "");
   }
   
   [MenuItem ("Custom/Show Mesh Info %i", true)]
   public static bool ValidateShowCount()
   {
       return Selection.activeGameObject;
   }
