If you're not comfortable playing with the .cr2 files, then you might not want to try this. It's not difficult, but seeing the guts of a .cr2 file the first time is scary. It took me less time to hack the .cr2 file than make the body morphs in the Tailor. *Make sure to save the hacked .cr2 file under a new name!*

Start with the Victoria 3 sr-1 character.
Inject the morphs you want to use.
Save the character in the library.

Now here comes the fun part:
Open up the saved .cr2 in a text editing program. (I like to use Textpad, but there's several good free ones out there. Don't use Wordpad unless you have nothing better to do for the weekend!)
Delete all the material settings blocks at the end of the file. (Delete the line that starts with material and all the "gunk" within the curly braces underneath it.)
Delete all the group blocks. (You'll find it under the channels section in each body part.) Here's an example:

<br></br>          groups<br></br>                      {<br></br>                   groupNode Other<br></br>                             {<br></br>                           parmNode PBMPregnant<br></br>                                parmNode PBMStretchArms<br></br>                             parmNode PBMStretchLegs<br></br>                             parmNode PBMStretchNeck<br></br>                             }<br></br>                   groupNode Transform<br></br>                         {<br></br>                           parmNode scale<br></br>                              parmNode xScale<br></br>                             parmNode yScale<br></br>                             parmNode zScale<br></br>                             parmNode yrot<br></br>                               parmNode xrot<br></br>                               parmNode zrot<br></br>                               parmNode xtran<br></br>                              parmNode ytran<br></br>                              parmNode ztran<br></br>                              }<br></br>                   }<br></br>

Do a find/replace on each of the following lines, replacing each line with just a space:

backfaceCull 0
visibleInReflections 1
visibleInRender 1
displacementBounds 0
shadingRate 0.2
smoothPolys 1

Save the file under a new name.
Load the hacked .cr2 into the Tailor as the base figure.
Load the clothes into the Tailor as usual and run the Tailor as usual.

Warning - you may see a lot of "-" morphs in the .cr2. Just ignore them.

Cheers!
