Question by Jeston · May 13, 2011 at 08:08 PM · materialdependencies

Select Dependencies on scene shows material not in use

I was doing some cleanup work on a scene that was a copy of another scene, and the big difference is an entire resolution change, meaning every object has been assigned a different material.

However, when i select Dependencies on the scene it still is referencing the original materials which I am assuming means loading an uneeded high rez texture.

I even wrote a script to search all nodes to find the material in question:

using UnityEngine; using UnityEditor; using System.Collections.Generic;

// // Editor script to find a material in the scene graph // public class FindMaterial : EditorWindow { public string MaterialName = "";

 [MenuItem("Window/FindMaterial")]
 public static void ShowWindow()
 {
     EditorWindow.GetWindow(typeof(FindMaterial));
 }

 //****************************************************************************
 // Recursive tree parser to scan all descendants of a tree
 //****************************************************************************
 public void ParseTransform( Transform node )
 {
     Component[] comps = node.GetComponents<Component>();

     foreach( Transform child in node.transform ) 
     { ParseTransform( child ); }

     foreach( Component component in comps )
     {
         if( component is MeshRenderer )
         {
             MeshRenderer mesh = (MeshRenderer)component;
             foreach( Material material in mesh.sharedMaterials )
             {

                 if( material != null && material.name.Contains(MaterialName) )  
                 {
                     Debug.Log("FOUND " + node.name );
                 }
             }
         }
     }
 }

 //****************************************************************************
 // Build UI For editor window
 //****************************************************************************
 public void OnGUI()
 {       
     MaterialName = GUI.TextField( new Rect( 50, 60, 100, 20 ), MaterialName);
     if (GUI.Button(new Rect(50, 100, 100.0f, 20.0f), "Find Material"))
     {           
         GameObject[] objects = Selection.gameObjects;
         for( int i = 0; i<objects.Length;i++)
         {
             ParseTransform( objects[i].transform);
         }
     }
 }   

}

And nothing is found. Does anyone have a suggested solution or is this something that I should disregard as a bug and it won't be harmful?
