I just love this sort of thing. I just finished Denis's (allstereo) tuts on Poser's Dependent Parameters and got a ton of in depth understanding out of it. This is one of the reasons I stay with Poser (despite it's instability, goofy interface, lack of new content, etc). You never see technical discussions of this depth for Daz. I guess they want folks to guess how it all works. This will go a long way with helping me rig my you-really-don't-want-to-know-but-it'll-be-for-sale-on-pervertosity-soon gizmo. Have you folks ever considered writing a book? B.L. Render's "Secrets of...for Poser 8" is still topical but getting long in the tooth.
Thanks for taking the time to write this.
