1 question - why are you saving a material as a Pose? That hasn’t been necessary since the release of Poser 5.
Poser material files are the way to go nowadays for Poser.
You’re forgetting DAZ|Studio users. Every version of D|S can use .pz2 MATs (albeit ignoring the shader tree stuff if it’s there), but only the very newest version can even see the Materials library folder. In all earlier versions it’s invisible and the .mt5 and .mc6 files useless without a bit of editing. Some people don’t want to upgrade, and some just plain can’t use the shiny new version. So making materials available as .pz2 files means everyone can use them.
No, I wasn’t forgetting DS users, I was answering the question -
Jaguarry3 was asking Poser users on how to add materials for our use, he wasn’t asking DS3 users on what they used.
In the Poserverse, we have been moving (slowly, ever so slowly, to quote Black Sabbath) way from Poser 4 requirements. We don’t need rsr files in 2012, but we still have people making them.
Poser has changed a lot in the past 5 versions, and most DS users aren’t aware of how Poser does things currently, just like I don’t know how DS does things.
