I'm not talking about making conforming clothing or how it works once conformed.  What is needed is information (probably speculative) on how one figure is conformed to another - that is, the algorithm or process.

Yeah, yeah.  It's simple - the matching body parts of the figures are put together.  But that's only if you are a good boy (or girl) and used the exact JPs of the target figure (maybe with the adjusted weighting zones).  I've seen plenty of conforming figures where things really didn't match up (because of scaling or joints nowhere near the target figure's or in different orientations or etc.), and yet Poser still manages to get them conformed properly.

My conforming algorithms are pretty good, but very complicated and tweaky.  And they still fail on a percentage of figures - especially shoes/boots.  For instance, the image shows a before and after - with color-coded bones to illustrate the mismatch.  This is Miki with the left Yulan Boot, unconformed on the left, conformed on the right (not tweaked).

Of course, this is my own limited-understanding implementation of how this might be done.  There is definitely something missing in my understanding that allows conforming to occur in Poser even in some brutal circumstances and fail with these odd cases with my algorithm.  And it would be nice to remove the oft-times required user tweaking and be able to get it right programmatically.

Thank you very much,

Robert
