From PPro to Poser 5 to Poser 6. Now I only Poser 6 since it came out. Poser5 collecting dust ontop the box which is in good shape. I need it though for Poser 6 (Product Number). My friend never used his PPro, so I used it for awhile. Got my interest so well. To the point I went out and Purchased P5 from Renderosity. Then now using Poser6. :-)
