Okay I tried the new algorithm and that seemed to work. Every time I apply a new pose the eyeballs stayed where they should. I think I also see what I did wrong earlier when I tried putting this directly into the pz3. A mistake on my part.

 

This has really saved me some time, plus I can use the same approach in the future. Thanks to everyone, and lesbentley look for a renderosity gift certificate in the mail from me.

 

Thanks all

Mark
