hank you for your kind works, FlyBoy.

I'll have to admit: I've been trying to do morphs in Blender on V4 but have run into your exact snag. Lisa Richie has a really excellent tutorial on how to accomplish this: I think it's in the tutorials section.

I wish I could help you but I can't - I'm in pretty much the same place as you. I've been meaning to finish my import, but then I got stuck into shaders and algebra and there's just so many hours in the day, and the family keep wanting feeding... sheesh.
