Most of what you see on DAZ (about 90%) is Poser ready as long as it does not say "GEN" then everything can be used in Poser, If it says it will ONLY work in DAZ then be sure it will not work in Poser, like some Poser items state "Will NOT work in DAZ". One of the rules for DAZ is that "what ever it is" needs to be Poser ready, That has been the standing policy for DAZ.  Now with DAZ4 it will use the Poser stuff as well but more and more DAZ seems to trying to create DAZ 4 only stock.  Do keep this in mind, "DAZ is FREE Poser is not" and looking for Poser stuff you are at a good site there meny others out there, as for me I will be sticking with DAZ even though I have Poser installed.
