Most heavy duty morphers I know use a major 3d app to do them. because the workflow is quicker. When you are making a few hundered morphs, you can;t spend 2 hours trying to make one, because you;ll never get done.

Most popular apps are lightwave3d, 3ds max, zbrush, c4d, and modo.

Fastest morphing tools are probably in zbrush, modo and lightwave 9.2.

What I can in lightwave in 3 minutes takes me 15 minutes in poser, and whith a lot of morphs, you REALLY need point level access. smalle details things like eyelashes, teeth n such can be hell trying to fiddle with in poser.

Way too many people take way too many things way too seriously.
