Quote - Only if you know the resolution of the adjacent parts, or are willing to switch them accordingly. Geometry switching wouldn't do this by itself, but it might be possible with dependent parameters, Python or maybe even clever ERC coding. Or, as seems more likely, Poser might fall down while frothing at the mouth, figuratively speaking. :) 

Yes, it's exactly what I was thinking. lol

Teorically everything can be done.

My idea was to give to the mesh an higher resolution and then manually adapt the boundary to match the low res version, load every hi-res part on a low-res full body (there goes the "lot of work").

The real number of body parts isn't so high, since hands and feets are "one" , no necessity to switch fingers or toes, only to/from wrists and ankles at high or low res body parts.
