I merge the graft to the main figure using the Geometry editor in Daz Studio, re-assign the added geometry to the hip of Jonathan.  then save as figure/prop asset.  Also need to convert the gens to blended weight prior to the merge.  The only kicker is that it only works as intended using DS4.10.xx.  Clothing conforms, hair fits, poses work,  some pose controls don't work (3DU Pose Architect, some do some don't).  FBM's need to be applied prior to merge, and basically any morph that moves the area that the graft is attached to.  Just dial in a value, any value except 0. I generally select the Actor in the parameter tab and set every dial to anything but 0.  Anyways, once saved in my own directory, I clear the scene and load up my saved figure, all the dials are the way they were set, zero the figure and save again as a character preset,  I save it using the same name and the original save gets over-written.  Load in Carrara and Voila.  The become stand alone figures, as in they won't accept other character morphs after the fact,  the idea is that you convert the character that you want,  add the morphs you need, and get rid of the morphs you don't need, just to keep the file size down.  But as I says, got to use DS4.10.  I've tried ever other version since 4.10 without success,  so now I just run DS4.10 as a plug for Carrara.  G8.1 preset by Misty was a challenge, but I think I got it to work,  I'll work on a proper working document to outline the steps with screenshots.   And yea I love OR4C.  I never use Carrara without it.
