Yes but the OP is apparently using Poser 4, 5 or Poser 4 Pro Pack. Hence the question 'Will he work in earlier versions?" When they say it requires Poser 6 that's usually because the product has been saved using one of the advanced features I mentioned which are not available in Poser 5 or below.

Thet doesn't mean the figure won't work in earlier versions, but you'll have to work to get the CR2 resaved with all morph data in the CR2 instead of a PMD file and all compressed files like CRZ and OBZ have to be uncomressed for Poser 4 & 5 to recognise them.
