I were successful in my experiment. Treemaker is POSER4's hidden function. But It not seem to get it to render with the image Because Line-polygon have no area. What a waste! I want to get it. I can convert line-polygon to normal square polygon. also I can generate UVmap. The pic is rendered in POSER.No post production work. Are you interested in my tool "HairConverter"? If so, I will upload the tool on my site within a week or so. POSER++
