On the center top right corner of the window that shows you the face map (center image that has "Texture Preview" above it. You will see two icons that look like folders above it. (One on the top left and one on the top right side) Click on the top right folder. Then change the name and save it where ever you want. I havent played with spawn Morphs yet but with the trouble I have been having I have also save them as a .pz3 and compressed Pzz file to make sure. Hope this helps
