Don't feel embarrassed at all. It is and always has been a lesson in futility for 99% of Poser users. Forums are full of these discussions and honestly no one has found a "correct" way of doing it. Some "say" they have had no troubles but cannot explain with any clarity at all.

Try all hints and advice but don't worry if you fail miserably and give up. I have given up and countless others have as well. It's probably best to download DAZ and render etc from within the program that invented it.
