How to select correct atlas prefab with atlas maker editor tool

[pek]

Hi there,

I have 3 atlas prefabs: 1 reference (named "UIPlayScreen"), 1 HD (named "UIPlayScreen@2x") and 1 SD (named "UIPlayScreen@1x"). I'm running Unity 4.0.1.

I can't seem to find how to select the atlas prefab I want and edit it in the Atlas Maker editor window. At some point I selected UIPlayScreen@1x and then opened the tool's window from NGUI -> Atlas Maker. It had correctly selected the prefab so I went ahead and made my changes (added new textures). I closed the window, selected the UIPlayScreen@2x and opened the editor again. The editor has not updated to what I'm pointing at (it's still stuck in the UIPlayScreen@1x) and I can't seem to find how to tell it to select the other prefab.

Any help?

Thank you.

Never mind, found it. It was the Select button. I thought that would select the material, but it turns out, it selects the prefab.
