Yes, it does include Morphs++, I thought the screenshot made that clear, the file in question is in the .../Runtime/Libraries/!Daz/Victoria 4/Deltas/Morphs++ folder and YES the "missing" file is part of Morphs++ and in the Morphs++ section of the shaping tab I can successfully use the Definition Slider which overlays the file that Daz thinks is missing. Note that there are several other dialog boxes for other "missing" files which follow this one. I can reproduce this at will, it occurs every time I try to apply a V4 figure on top of the base 4.2 figure. I can morph vanilla V4 to my heart's content. but I cannot apply predefined morphs from inside a purchased add-on V4-based character such as Sabby-Amber.

I am using 4.9.3.166.

I am starting to worry about what Daz is using in the path BEFORE .../Runtime/Libraries/!Daz/Victoria 4/Deltas/Morphs++ ie is it obeying my chosen Content Directory Manager selections, which are not the same as the defaults. After decades working in tightly policed corporate IT policy, I cannot/will not put Daz material in Documents. Daz stuff is data files, not documents.
