I am sure you saw this, but no harm in repeating it here:
The included smartpropped overskirt and oversleeves use dynamic cloth simulation settings for Poser and will NOT work in DAZ studio!
Anything in the set which says ‘conforming’ will be able to be used in DS by using the ‘Fit To’ option.
Poser Dyanmic clothing is not rigged, therefore it wont conform, it needs to be draped in Poser’s Cloth Room to get the effect. In theory it is possible to rig it in DS, and then make it conforming, but I imagine that the reason this ins’t conforming in the first place is because it would be a nightmare to produce all the required morphs to get the same effect as using Poser Dynamic Cloth.
DS uses the Optitex plugin for DS Dynamic Cloth, and it is nothing like the same as Poser Dynamic Clothing, and thereofre wont work in DS, sorry.
