Here is a tutorial re step rendering but what i suggest you do is play.. click click click everything and see what see what it does Daz Studio is a very simle app to use and you can get some good looking images.. as for posing just click on a body part and turn the dials.. you can even get clothing and or props that do not have inbuild morphs to fit.. just carefully scale certain parts ( scale is in the paramater dials ) and trust me if you find D|S hard to use dont bother with Lightwave
