We created an atlas with images that have the naming convention Item_WIDTHxHEIGHT:
Btn_Close_48x48
Btn_Goals_48x48
Btn_Options_48x48
Btn_Pause_48x48
Btn_Play_48x48
The artists then decided that the images should be larger, so scaled up the images. We renamed the files to match their new dimensions:
Btn_Close_64x64
Btn_Goals_64x64
Btn_Options_64x64
Btn_Pause_64x64
Btn_Play_64x64
Unfortunately, the NGUI atlas stores the source image
names in the atlas' prefab, instead of the source image
GUIDs which means that all of our UIImageButtons and UISprites broke.
Is there a way that the GUIDs of the images could be stored in the atlas prefabs instead of the image names? Then if we rename the source image names, the atlas would still point to the correct images.
