I was wondering if it would be possible to export the items alone in a future update. I wanted to mix and match some hair, but it's a bit difficult since the body template gets in the way.
I think we can add some advanced options to the export preferences sidebar, which contains a checklist of the currently available layers; so people can simple check and uncheck what they want to see in the exported image. Should be useful too for people who want to split the face layer to a different file (seen those in a lot of Japanese visual novels).
Thanks for your suggestion!
