I have a simple-ish but weird question. I make use of the atlas-less form of Spine (discrete pictures as the attachments to bones). I use one of the HTML Spine runtimes.
I have been able to develop my Spine Editor project pretty nicely. However, in the final product (let's say its a game) what would happen if I subbed-in some higher-resolution images/textures/attachments PNGs in the final project? Of course they would have the same aspect ratio. Do you think Spine would generally handle that ok? I imagine Spine would just size them down to the expected size defined in the skeleton file.
