I won't claim to be a great expert at morphing, but here is my twopence. 1. I usually use ZBrush for face morphs, someitmes I use Poser magnets. I mostly use poser magnets for body morphs. 2. There are some tutorials on making morphs using AMORPHIUM, RHINO, and Poser Magnets, at Morph World, see link above. 3. You can make morphs in almost any 3D modeling application, but it is more convenient if the application can export Wavefront Object format (obj). 4. No.
