[BUG] Mesh Collider keep getting lost whenever i disable the gameobject for a while

So yeah, whenever I disable a probuilder mesh for a while (in editor), and turn it on again after a while, it missing it's a mesh in the mesh collider component. Please fix it

 

Anyway, for anyone that looking for a solution, this is mine.

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. public class MeshRest : EditorWindow
5. {
6.     readonly string recordButton = "Rest Meshs";
7.  
8.     [MenuItem("StaviTools/MeshRest")]
9.     static void Init()
10.     {
11.         MeshRest window =
12.             (MeshRest)EditorWindow.GetWindow(typeof(MeshRest));
13.     }
14.  
15.     void OnGUI()
16.     {
17.         if (GUILayout.Button(recordButton))
18.         {
19.             object[] obj = Resources.FindObjectsOfTypeAll(typeof(MeshCollider));
20.             foreach (object o in obj)
21.             {
22.                 MeshCollider g = (MeshCollider)o;
23.  
24.                 //if there is no mesh in the meshCollider:
25.                 if(g.sharedMesh == null)
26.                 {
27.                     Mesh test = g.transform.GetComponent<MeshFilter>().mesh;
28.                     g.sharedMesh = test;
29.                 }
30.             }
31.         }
32.     }
33. }

 

thank you so much! this happened to me, i guess because i had disabled a large number of probuilder objects while working on a different section of the game world and then suddenly my game was very broken and i had no idea why

then i wasn't sure how to assign the mesh after trying several things, so this script worked great for me

thanks for helping me fix my game!

 

Hey, I soon discovered that MeshFilter also loses it's mesh, that's more problematic. I did found a simple solution.
Ctrl + D (copy and paste you world gameObject, and delete the previous one)

Good luck with your game
