It was only the one figure it was failing with. Renithra, the little elf boy. I set it aside and started another project which I didn't have the same problems with (I had different ones, but I'll get back to that.) I tried it both ways, with and without raycasting, and I tried changing the distance cutoff as well. Some of the morphs are copying, and the ones that do look fairly good, but the vast majority are not. I used Michael 4 for the comparison, maybe not the most obvious choice but he's the figure I have the most morphs for. I am unfortunately away from my computer all weekend, it's a desktop one so I can't take it out of town with me. I left the number of connections at the default. I aligned them very closely, better than the first two, I was being perfectionistic about it and took my time.  On the material screening, I started out conservative and gradually added more parts. That's about all I can tell you from memory, I hope you can extract some meaning from it.
