You need separate maps for the prop and the figure so that they don't share the same map. I thougth that Mike had separate maps for head and body. Haven't checked lately. Do you know how to change the maps from Poser? If so check if you can change the map of the head to the map that contains the lion's head. That should do it. I think.
Maybe I'll try this on my system to see if there is easier way.
uvmapper.com has tutorial page. Only one is for the free uvmapper. All tuts are in pdf format.
There are other uvmappers you can google but I think you'll find the uvmapper is still one of the best ones out there.
Hope this helps.
