I had this thread up already, and I am unable to find it now. (Dissapeared) The problem is I am on a project. Making a prop in poser, and I export it as an object file. Then I import again, adding fixing, and also adding the same obj file with the previous, to save work. Later I find my system slowing down, each time I import the Obj file again. The harder my system works in Poser. What can I do to fix this.
