Progress:  got the geometries stripped out of the CR2 & PP2 files.  Got the origin points and angles set.  Then I loaded the resulting library files into a scene, conformed the boots to Roxie, posed her, and then articulated the skate trucks to fit the floor.  The test renders have finished.  Everything seems to work "as advertised".  I'll get it packed up as time permits.  Try to limit yourself to a Z-rotation (side-side tilt) of the trucks/axles of not much beyond 20 degrees.

     By the way, the revised dress and panty are more poly-efficient now and they cloth sim much quicker now.  So, an updated pack with the leafy dress, panty, and slippers will also be appearing in the freebies soon.

Argh!  I can't post a clickable thumbnail, nor can I set the display size of a linked picture?!?
