"Applying fur to a polygon or subdivision surface model is similar to applying textures in that the geometry needs a specific arrangement of UVs so that the fur looks correct when applied to the model. (UVs are points that correspond to polygon/subdivision surface vertices and provide the information needed to map fur to the object.) For details on creating UVs, see the Polygonal Modeling guide or the Subdivision Surfaces Modeling guide.

The UVs must be laid out so they are non-overlapping between 0 and 1 in the texture space. To achieve this you can use one of the following to instantly lay out your UVs:

* Automatic Mapping
* Layout UVs menu item in the UV Texture Editor
By default, Fur uses the UV layout in UV set map1 to map fur descriptions to polygons and subdivision surfaces, but you can change this in the Relationship Editor. For details, see Select which UV set to use for Fur (polygons only)."
