Quote - I have used the Zygote bear from Poser 5 and it must be the same as the DAZ bear.

It's not.  Zygote and DAZ used to be one company, and many early Poser models were made by them.  So the meshes are related, but not the same.  I'd guess that's your problem.  You need the bear for sale at DAZ, not the one that comes free with Poser.

Also, there are different versions of the Poser animals.  I can't remember when it changed - Poser 7, maybe? So maybe that's why Bob got a different result trying to use the Poser bear than you did?
