most poser created items in the store will work in daz studio to a minimum of ds2.3 unless they are poser dynamic or poser materials,

 

i'm a daz user mainly ( havent gottten poser in any manner) and most of what don't have mention of works in ds2, ds3, or ds4 will work in ds any version, and if the vendor has ds files they will supply them to the purchaser voluntarily and readily.

 

if this helps then i'm glad to help if it don't then asking if the vendor will try would be up to yourself and i'm sorry i couldn't help.
