Phil Thank you  for your help. You are a Poser Master. I am not making a full body morph. I am making something like a bulging bicep muscle on left and right arms only.  And I am working with the full V4 character in Lightwave. Then I bulge the left and right arms, save this in Lightwave format then export the model  with the morphed arms as an OBJ file. Then with my original V4 figure in my poser window I select V4 hip and in the parameters window I select "load morph target" I select the OBJ. file I made and hit load. Thats where I get the  error message. I guess I assumed that poser would interpret the geometry and add the morphed geometry to the original figure since I did not add or subtract any points. As I said I don't have any experience with making CR2 figures from scratch. But I have made many  props, and textures. I am getting some other replys to my original question , It would appear that I am not doing something correct in telling poser where to or what part to apply the morph to. Your reply explains a lot I see that you cannot just export one V4 body part such as an arm, make a morph and import it back to poser. I assume that I could do this work with the Group Editor, but I find it akward to use. could you explain more to me about your Poser tool box utility or how the process unfolds in making a morph for a CR2 figure. I know that your time is valuable if you have time to explain this. But I really would like to know more about how this works.  could you direct me to a forum or tutorial I would be very grateful that talks about this in some depth.. KNOWLEDGE IS POWER
