We've just been manually moving all the slots once we import an export from Photoshop, but I'm starting to wonder if we're missing something.
When you make a PSD and export it and import in spine it's always "up and right" quite a ways and you have to drag all the slots to make sure it's properly positioned on the root bone at 0,0 in the grid so they are grounded properly.
2nd problem, If you then make new images in the PSD is there any way to export and import these to make sure they line up? You have to manually align and drag them to place instead of what's exactly posed in the PSD also.
