Atlas Maker crashes

[bkinsey]

Just wanted to let you know that the UIAtlasMaker.cs script has crashed on me a couple times.

1.         Dictionary<string, int> GetSpriteList (List<Texture> textures)
2.         {
3.                 Dictionary<string, int> spriteList = new Dictionary<string, int>();
4.  
5.                 // If we have textures to work with, include them as well
6.                 if (textures.Count > 0)
7.                 {
8.                         List<string> texNames = new List<string>();
9.                         foreach (Texture tex in textures) texNames.Add(tex.name);
10.                         texNames.Sort();
11. ---->                   foreach (string tex in texNames) spriteList.Add(tex, 2);
12.                 }
13.  

ArgumentException: An element with the same key already exists in the dictionary.
System.Collections.Generic.Dictionary`2[System.String,System.Int32].Add (System.String key, Int32 value) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/Dictionary.cs:404)
UIAtlasMaker.GetSpriteList (System.Collections.Generic.List`1 textures) (at Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs:228)
UIAtlasMaker.OnGUI () (at Assets/NGUI/Scripts/Editor/UIAtlasMaker.cs:963)

When the crash occurs I am unable to click on any new tabs in my editor, for example I cannot open my Hierarchy tab.

Opening and closing the Unity Editor fixes the issue, but maybe the code should more gracefully handle this. Not sure what the problem is, I just added a bunch of png files into my asset folder from file explorer, and then clicked on Unity, which attempted to catalog/load the images, and that's when the Atlas Maker crashed.

Based on the exception, you seem to have two images named the same, which is why you're encountering an issue.

I'm having problems with Atlas Maker / crashing too

I'm with Unity PRO 4.5.5f1, OSX Mavericks and NGUI 3.7.5

In my case Unity crashes every time and I'm not able to create new atlases, please help me here!

* I've reinstalled Unity
* I've downloaded the latest version of NGUI
* I'm working with new projects, with only NGUI imported
* I've sent bug reports to Unity already regarding this issue

1) Create a new project
2) Import NGUI
3) Click NGUI > Open > Atlas Maker > Click Atlas Dropdown
--- Error in console ---

Other case:

1) Create a new project
2) Import NGUI
3) Search for "Backdrop" bitmap
--- I've tried different configurations here, results are the same
4) Right-click it > NGUI > Open Atlas Maker
5) Click Create

I think something is wrong with your Unity install there. I've never seen those issues before and no one else had anything similar.

[Fliperamma]

Yep, I've already tried to reinstall but no success here... maybe I'll need to format my Mac to solve this

[Fliperamma]

Formatting my Mac solved the crash problem (Which is amazing, it was impossible to work) ... but still ... no Atlas being generated.

I'm stuck with this error (which was already happening before):

UnityException: Texture 'OpenSans-Bold-48' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.

I've tried to change the textures import settings / type to "Advanced" and enable "read and write" but as soon as I press "apply" the texture goes back to "Sprite (2D / uGUI)"

Maybe my project is corrupted in some way? Any advice here?

[ArenMook]

Is the texture file itself readable? Maybe you have it marked as read only?
