Hello, I am really sorry to trouble you and I apologize further if this has been answered before. I've looked around for a few days and couldn't find much help on the topic.
Some context: I've made a "paperdoll" skeleton which attachment textures are meant to be swappable on an individual basis, This is not so much for re-skinning but customization of pretty much every part, out of hundreds of parts.
This, of course, does not fare well with atlas repacking, which I understand is very efficient and convenient for 99% of projects. In my case, however, it's not viable for the aforementioned reason.
From testing, and as I understand it, it would be possible to manually edit the atlas.txt file to do exactly this, by treating each image as its own atlas "page". But lacking an automated process, and considering the skeleton may have to be updated and re-exported, manual editing would become an almost Sisyphean hurdle.
The behavior I require is pretty much how skeletons are handled at playback on the editor.
I understand why the atlas packer is in place, I get it makes a huge difference when it comes to resource management. But for my specific case efficiency is not an issue, ease of customization has full priority as I'm not exactly making a mobile game and the whole point of what I'm trying to achieve relies on texture customization.
I just wish to know if there's a GUI, CLI, or any solution to this I've missed. I'll take workarounds too, I'm not picky.
Thank you.
