You can attach fur to surfaces automatically when you create the fur description or you can attach it manually after you create a description.
You can attach more than one fur description to selected surfaces. You may want to do this if, for example, your model requires fur with different lengths or textures. For example, a horse’s body hair is shorter and stiffer than the hair on its mane.
If you attach more than one fur description to a surface, only the feedback for the last assigned fur description displays. For details on switching fur feedback, see Hiding and showing fur feedback.
