ZhouuzZ I'm sorry to hear you're having trouble. Unfortunately, I don't quite understand exactly what operation you are talking about, as the terminology is not accurate. Do you mean packing textures by "export a picture"? Or are you having a problem with the coordinates not matching when you unpack a packed texture atlas page and put them in the images folder to use them? Also, I would appreciate it if you could briefly tell us for what purpose such a workflow is needed.
