... It was difficult to me to translate "greeble" or "nurnie" to my language in the proper way, if I'm not wrong, you want to add props to a part of a figure. On Wikipedia greebles are definied like those object on the exterior of a space ship made to break the linearity and made to look like working objects, to me it looked like the definition of those panels like those of the space shuttle.
In any case, if you want to modify the original obj adding greebles, it's something that I've tried in the past with poor results, it's not as easy as it can appear and I finished parenting the object to the body part. Specifically, with
Posy I'm using eyes and teeth from a different model. Thinking about it... You could do this: for example you've a car figure and you want to add greebles to the front bumper: export the bumper as obj, modify it, load the model of the car, import the modified obj, place it exactly on the original bumper, select the original bumper and in
Poser choose object/replace body part with prop.
in mechanical object it should work fine, when you export/import just unflag all the options and you should have the obj placed exactly where it should be. In human figure parts it works "worse" because you loose all the morphs... But for example eyes works great and the teeth can be simply parented...
In this case, for me it would be simpler to move the figure to the final pose for the picture, with the morphs already applied and use the same method, using the figure like a mere obj... Obviuosly you won't have a fully functional modified figure but you can make the picture easily . (
