Will we have the possibility in the future update of krita to have saved file in csp format?

The actual layer stuff is not public

The actual layer format for clip studio files is not documented, but it’s pretty fun to actually look inside a file, and see, for instance, how they store text: it’s just plain text with hard-coded linebreaks, like in Krita, and a separate field in the database for the font for that bubble. As for brushes, I doubt that Clip Studio brushes really have more parameters than Krita brush presets.

And I also remember seeing somewhere that CSP encrypts most of their data with a key embedded in their software and while it’s possible to extract you can sail into anti piracy law waters pretty quickly.
