Atlas Leak

[myprabath]

I do have atlas leak in my current project.
so all the Atlases are inside memory after its loaded.
i have scene specific atlases so a given scene have specific Altus.

I found few references initial search and clean up. but still i can find the atlases are not  getting release soon after scene been unloaded.

now what I'm tying is force to unload texture from UI atlas material. Its worked and now i can not see the atlus texture in memory but that makes a UISprites and other UIWidget derived object gray or white. but if i deactivate and enable(from inspector) they are getting refreshed.

so can some one help me here.

Unload texture by,

1. UnityEngine.Object[] Objs1 = Resources.FindObjectsOfTypeAll(typeof(UIAtlas));
2. List<UIAtlas> totalAtluses = new List<UIAtlas>();
3. foreach(UnityEngine.Object tempObject in Objs1)
4. {
5.         UIAtlas atlus = tempObject as UIAtlas;
6.         Resources.UnloadAsset(atlus.spriteMaterial.mainTexture);
7. }
8.  

Reload textures By,

1. Object loadedAtlusTexture = Resources.LoadAssetAtPath("/Atlases/"+atlusName, typeof(Texture2D));
2. atlusObject.spriteMaterial.mainTexture = (Texture2D)loadedAtlusTexture;
3. atl.MarkAsDirty();
4.  

I do have latest NGUI

Before unloading the texture, set atlas.spriteMaterial.mainTexture to null first. You can't unload things that are referenced.
