Hello

As an old member of Renderosity i remember you,Arcady

Welcome again!!

Using Poser since version 2 (now Poser pro 2014) and DAzStudio since its debuts, i suggest you now to concentrate your learning on free DAZStudio pro 4,6 .Anyway all Poser stuff are working good with it. And the rendering is good with good lights  ;you can also use Reality plugin for Luxrender output

Using also Vue d'esprit infinite (version 2014 now) , i can say that it possible to import files from DAZStudio if export in another format (like obj) but i have variable results from this exportation-importation process .Poser files are more easily imported in VUE with some ajutment in bump and hightlight parameters of the materials. Even with Skin vue plugin for human characters, i think the Vue road to render is justified if you really need to have characters on the landscape not for just rendering

But i admit that Poser stuff are very good now and many excellent stuff from  RDNA site are principally for Poser .The DNA  Render Studio serie of products  is very good

Bonne chance!
