You know not what you ask. But here goes... A typical cr2 file contains:

• An obj reference [figureResFile]
• A listing of the actors [actor xxxx:#](here it tells which object group from the obj file belongs to what body part, or defines what custom geometry to use for that body part)
• A second obj reference [figureResFile]
• A second listing of the actors [actor xxxx:#] (under each actor is where that the joint parameters, morph dials, and all the other dials are defined for each body part)
• The figure section [figure] (this is where parent-child relationships, IK chains, weld commands, material settings and other general properties are defined.

Okay, you really only need to deal with the second actor listings for this. I would suggest against just copying bits and peices of a particular actor until you are familiar with what each bit and peice does. I would suggest deleting the entire actor from your new cr2 and then copying the entire actor from the old cr2 into its place. Afterwards you can open up the "channels" section under that actor and delete any morph targets you want to get rid of (Identifyable with their "targetGeom xxxx" tag). The other thing to watch out for is the figure numbering. If your new cr2's actors end in a ":2" and your old cr2's actors end in a ":1" you could run into some trouble when copying stuff over. You would need to change all those ":1"s to ":2"s, which can be done somewhat easily with a find-and-replace in Edit Pad or whatever text editor you have available. Hope this helps.
