I think this was some unfinished feature that got left in by accident or something. It was never fully developed. Too bad, it was a great idea. I never got anywhere with it. I played with it for a while, but since it didn't render, it was sort of worthless to me. I downloaded FurFur, but never tried it. I heard others say that it turned the "hairs" in to triangles, so it lost its effect of hair when rendered. Melanie
