Is there a Mac equivalent for Morph Manager yet?

Not yet, I'm afraid. But be patient, it will be done. In the meantime, you can already copy a morph to a different model simply by exporting the body part as "morph target" from Poser4 (set the individual dial to 1, all others to 0 - or create a new shape with mixed settings). Then open the exported .obj in the new model as target, and give it the same dial name that it got before. Not the most convenient way, but it works. An even more powerful way to export morph targets is Compose (which runs on Macs as well), it offers a lot of very advanced possibilities, but it is a bit tricky to install and use. There is a tutorial that explains it all, follow the link from my homepage: http://www.main-rheiner.de/homepage/soft.rabbit

Thank you Martin, I'll try the export. I'm a newbie to Poser 4 so I think I'll bypass Compose for now.
