Quote - inability to morph across group lines aside, the morph tool is incredibly underrated. so few people use it :(

rather than making face/figure morphs i think that its real advantage is being able to quickly touch up clothing pokethrough, joints, flexing muscles, creating expressions, etc.

making it morph seamlessly across group lines would be amazing... unfortunately we probably wont see that till poser 10 :)

I've gotten pretty good at working around this.  I just use move relative to the surface on both pieces, then switch to move relative to screen and adjust the morphs only at the silhouette to keep them smooth.  Then I might use the smoothing tool at the edges.  It's a little more work, but I am very glad I forced myself to make it useful.
