Yes, but in rendering, there'd still be a seam line unless the garment was properly mapped to be filled in that way. Skirts are easiest (basic tubes). In order to have the garment look like it was made of cloth, you'd want some areas (shoulders) to look as though they were seamed. Unless the person is wearing an animal skin with his arms and legs through where the original beast's were, there will be some evidence of joining fabric. Even a knitted garment will reveal how the sleeves are set in despite being knitted in one piece. Carolly
