As far as I can tell, it is impossible to save the new sky color mask effects in (Raw 14.0), either by itself or with other changes. Opening into jpeg or saving back to RAW fails to record the change. Other types of changes work and are saved upon opening in jpg or back to RAW. If I'm missing something, then this new feature is very poorly designed and documented. Using Windows 10, 64 bit, 8 gigs RAM.
