For something like that, barring one coming out from Martin, if I were rendering a static image, I’d probably export the posed figure as an obj and skirt/kilt as another one, then import it into Blender and run a cloth sim on it…then freeze and export.
Not the easiest option, but on something as esoteric as a ptergyes, the likelihood of a true dynamic option happening anytime soon is low…no offense Martin, but I think working on more common/popular items has higher priority than historically accurate armor, right? (though, I’d like a set, too…for Gen4 or Genesis…fiddling in Blender that way gets tedious).
There are a lot of sets in the store with a roman/greek feel but they are all absent this one staple or have a some-what, sort of-close-to-but-not-quite working Ptergyes. Yet, if you look at movies like Gladiator or series like Spartacus, they are all over the place.
I would more likely export to ZBrush and use the transpose tool on it, but I would much rather have the option open for DAZ inside the program and ESPECIALLY if I wish in the future to animate it.
I dare say a Ptergyes along with a well done roman toga and senators robes may well give way to some Greek/Roman historical fiction. *smile*
Gladiator vs. Spartacus anyone? *chuckle* Or I, Claudius versus Caligula.
