"...unless you subtracted those deltas from the [new deltas]".

Right.  What's really happening when you fill the verts list?  I suppose one could just generate a list of vector objects as before, in your earlier example, using worldspace or UVs or whatever we haven't accomodated.

Don't mind me.  I'm trying to grasp a new system and its parameters.  I'm very pleased with all of this.  I'm still trying to understand how my current approaches will need to change.

I have a copy of your unimorph script, and I've pulled it out to think about it now and then.  A process like that could be useful for multiple actors in TDMT.  In shrink-wrapping, I also need to be able to accomodate actors which aren't part of the unimesh for a figure.  Or perhaps there's no figure at all, and I want to shrink a sphere around two spheres and a cone.  I don't know.  At any rate, I'm thinking about an indexing method similar to but more flexible than the unimesh indexing.  Hmm, hmm.  But wait... don't read this paragraph, okay?  Because I'm going on about it after you told me not to carry on about the matter....  Cough.

All is well.  :D
