Well, we all have the same problem - but that has to do with very strange settings Poser is doing. Black highlights for example - not very "real world" i think but Poser wants to have it like that. Vue imports that correctly but it looks not nice because of the different rendering methods. How about doing the material settings right in Poser so that you don't have to deal with it in Vue? I sometimes do that, i know that i will not render the objects in Poser so it is not a big deal. Just a little test sequence what needs to be changed into what and you are on the good side.
