If you are just going to use it in Poser, try this: As you get each part the way you want it, parent it to the wall or whatever is central, or do a chain if that is more appropriate. Select the central object and save the prop to the library. If you check the correct boxes during save, you can do the whole k&k as a single prop. I would then come back into Poser just as it was saved. If you want to do more extensive texturing: easier - export each object separately (when it is fully constructed but not yet placed) as a WaveFront OBJ and open it in UVMapper-map it- save model -delete source prop in Poser -import the mapper version into Poser - place it and do the above save to Library. I think you can also export the combination as a single prop from Poser. The grouping tool is not what you think it is- among other things it lets you assign new materials and cut a group up into more than one group - but it is not the kind of grouping tool that is in RDS or Carrara.
