FYI, bet you did not know that as a vendor you are also asked to pull the zipped file from an older version of Poser so that when a customer unzipps it, they don't get that little message," this was created in an earlier version, Poser will attempt to load it."

Example, when I create a new product and get it ready for  users, it was requested that I put it in an older version of Poser so that the customer did not get that message, so vendors like me use older versions alot to package and finish the creating process in (my example) Poser 6.

You can see this if you look at the .cr2 files from the library, it will say at the top, Poser 6.

As a poser user, I use the older versions of poser to help create a product and the newest just to see how it renders and if it works, checking to see other little issues.

Vendors really know alot about the mechanics of Poser just because of all our testing of products and getting them ready for customers.
