"Or maybe you have thousands of attachments and it would not be feasible to load all the images when the skeleton data is loaded. In this case you could defer loading images until later, once you know which attachments will actually be in use."
Can somebody tell me how to do this? Our game has 2 different bodies (bones), and lots of sets of cloth. I am thinking maybe I should organize cloth parts using skin. And we can have hundreds of skins. But I may only need less than ten for one client. How do I avoid loading all the images in the atlas which is such a waste?
