I mostly hear ( Read about ) rendering, materials but about the very needed parts almost no one is talking about, nor asking for them. The assets them selves. all seems to be stuck a decade ago. sure there might be enough old figures around as long V4 is supported. But what will Poser be with just a render engine loads of texture settings and no new 3D models. Well sure you might start to make texture settings on primitives. I personally think that the main fun part on Poser is the Posing of 3D models and not spending days on figuring out texturing and running hours of renderings just to get a right texture setting. Well the name already tells it ( Poser = Posing assets ) 

You can run P4 and get stunning render results but well you need a stunning 3D model or are we arrived on a point where majority of users only Want render cycles. For these a better hobby would be to take a camera and go out to make some realistic Pictures, there a 3D model is not needed and the pictures would look most realistic.

I might be wrong and there are just almost no 3D model creators left for poser that could talk about this matter, so what remains is only to talk about texturing the remains.
