As I said, that is cool but in D/S there is something called Decimator which from my limited brain pan seems to reduce the density of the mesh for those times lower rez images can be useful. Does Poser have anything similar?
So Poser added a feature like that in the 2014 GameDev version and it's in Poser Pro 11 as well. Under either the Figure or Object menus you'll see Reduce Polygons if you have either of those versions. It gives you a popup like this:You can reduce the poly count on objects and on individual body parts (it's in the Object menu, and you can tailor the reduction amount), but you can't do a whole figure in a single process (unless someone's written a script for it or something?)
So you can either use the slider, or even type in a number, and also deal with morphs etc. It's not a bad little feature.
