Question Draw on Texture2d during OnPostprocessAllAssets to disk

Hello,

I came up to the need of drawing some pixels into a Texture2D to solve some artifacts created by some filtering.

I have go trough the documentation and I can't manage to get the changes done to the disk asset itself.

Have anyone face a similar problem in the past?

This is a simplification of the code I have right now:

Code (CSharp):

1.     static void OnPostprocessAllAssets(string[] importedAssets, string[] deletedAssets, string[] movedAssets, string[] movedFromAssetPaths, bool didDomainReload)
2.     {
3.         foreach (string asset in importedAssets)
4.         {
5.             if (!(asset.Contains(_atlasPath) && asset.EndsWith(".png")))
6.             {
7.                 continue;
8.             }
9.  
10.             Texture2D texture = AssetDatabase.LoadAssetAtPath<Texture2D>(asset);
11.             texture.SetPixel(1, 1, Color.black);
12.            
13.             texture.Apply();
14.             AssetDatabase.SaveAssets();
15.         }
16.     }

Thanks!

 

hmmm not sure but maybe AssetDatabase.SetDirty before saving might help.

oh, is the texture read/write enabled? See inspector

 

Thanks for the response.

Yes the Texture has Read/Write enabled, if not it would throw an error on calling SetPixel.

AssetDatabase.SetDirty does not exists so I suppose you mean EditorUtility.SetDirty. I tried it before the SaveAssets call but it's unfortunately not working.
