Quote - It doesnt seem to access any obj file whatsoever

The geometry is for some reason embedded in the file in those geomCustom sections.

The same process (more or less) as for props would be required -> http://artzone.daz3d.com/wiki/doku.php/pub/tutorials/poser/poser-misc42

The wrinkle here is that you need to do one OBJ for each customGeom.

The alternative would be to combine the seperate OBJs making each one a group and rerig to create a new CR2 that has body parts corresponding to those groups (I suspect this is only worth attempting if externalising the seperate parts doesn't work).

Once you have an OBJ or OBJs you can map those and add materials etc.
