Objaction Mover is in free stuff, check under Utilities (3rd page in) or do a search for Maz, who created this wonderful programme. What Mover does is encrypts and decodes OBJ files. If you create a garment for the P4NF which relies on a modified version of a Zygote mesh, you cannot distribute the modified OBJ becuase the copyright belongs to Zygote. But, that would mean you can't distribute your garment 'cause no-one else will have the modified mesh. This is where Mover comes in. Using the original unmodified mesh as a seed, it creates an encoded PCF file for your modified mesh. You can distribute this PCF file (non-commercially) with the CR2 of your garment. When your garment is downloaded, it can be decoded by using Mover again. However, you've got to have the original, unmodified mesh on your computer to decode it. In this way, it prevents the distribution of Zygote's copyrighted mesh. Can't help you on the book I'm afraid Paul
