When you set the scale at Data Import
, it scales only the skeleton data (position of bones, attachments, etc). When using this setting, it's usually because you have images that are a different size. For example, your images are 25% the size of the skeleton in the skeleton data, so you use Import Data
with 25% scale so your images and skeleton data match.
When you export from Photoshop, the size of the images and skeleton data match. If you then use a scale != 1 during Import Data
the skeleton data will be the wrong size.
My guess is what you want is to set a scale when you export from Photoshop, in the PhotoshopToSpine script's settings dialog. For example, if you set a scale of 25% there, then the images are scaled down 25% from what is in the PSD and the skeleton data is also scaled down 25%. You would then use Import Data
and specify a scale of 1 (which is 100%).
