I've started working on a tutorial. It will walk through the entire process of putting together the images posted above. (I dislike tutorials that seems to think you understand everything except what the tutorial focuses on.) As such, the tutorial will include the blend nodes and all of the other things used. I'm not going to claim it is going to be a very well written tutorial but it should be useful to both novice Poser users and possibly even the advanced ones. At this point, about the only thing I'm certain of if that the tutorial won't be short. I figure people can ignore whatever parts of it they want to. If there is anything else people want included in the tutorial, please let me know. Once I finish the tutorial, I'll post it on my website and put a link to it here.
