Greetings Terry! I started with poser but only use Daz Studio now, mainly cuz the daz store is way more supported. I cant say I remember the plugin you mentioned, did you mean human maker 3d? There were lots of 3rd party plugins out there and some were actually quite good for the victoria 4 generation etc! I remember another called 3d person maker and then there was also realistic face maker and random face generator etc, they all had similar names!
It’s a great time for digital art with so many new tools out there. There are also tons of good tutorials for daz studio that take the guess work out. All the best!
