Hi it's me again, hope you don't mind another back-to-back update suggestion :P

I don't think pribambase currently has a feature to automatically transfer an image modification from blender (through image editing/texture painting) over back to asperite. Sometimes I find it easier to make small tweaks on the actual 3D model, but those changes don't get ported over and are overwritten after making changes in asperite again. 

The solution to this is saving the image and reimporting then resyncing to asperite. Which isn't very fast and seems to break transparency too (though that might just be a blender setting I have wrong that saves without alpha, I have a workaround anyway)

in most cases there’s no way to revert exported texture back to original sprite. at the very least, blender has to add layers support for that to be possibly possible.
