What is the workflow for normal maps?
Please correct me if I'm wrong, but it looks like we need to take the atlas generated by Spine, use a tool like Sprite DLight to create a normal map for the entire atlas and (likely) tweak it manually.
If we later add an image in Spine, the atlas is regenerated and we'll have to create the normal map again?
It would be great if there was a way to import normal maps into Spine alongside the regular sprites. Either with a file naming scheme, or from a Photoshop file (additional layer group for normal maps or something), and have the export generate a normal map atlas.
