- Primitive Type
-
Controls the kind of primitive that the Description generates.
See Primitive Type in the Spline attributes topic for details.
- Control using
-
Sets whether Attributes or Guides control the location and shape of primitives. (Groomable splines are controlled by attributes and Ptex maps created by the grooming tools).
- Guides
-
When selected, guides control the placement and shape of the primitives. After placing guides on the surface of the mesh, you can move, shape, and scale them to influence the appearance and behavior of the primitives. See Guides.
- Attributes
-
When selected, the groom is driven procedurally using attributes and expressions. No guides or guide interpolation is used to place or shape the resulting primitives. See Control primitives using attributes and expressions.
- Length
-
Controls the length of each card along one of its dimensions.
When Control using is set to Attribute, this value sets the primitive length. When Control using is set to Guides, Length scales primitive based on the guide length.
- Width
-
Controls the width of each card along one of its dimensions.
When Control using is set to Attribute, this value sets the primitive width. When Control using is set to Guides, Width scales primitive based on the guide width.
- Tilt U
-
Tilts primitives away from the surface normal. 0 is no tilt and 1.0 is a 90-degree tilt.
- Tilt V
-
Tilts primitives away from the surface normal, but at right angles to Tilt U.
- Bend U
-
Controls how much each card is bent in the U direction. 0 is no bend, and 1.0 is a 90-degree bend. Cards bend in two places.
- Bend V
-
Controls how much each card is bent in the V direction. 0 is no bend, and 1.0 is a 90-degree bend.
- Bend Param U
-
Controls where the card bends in the U direction. 0 is at the center of the card, and 1 is at the edges.
- Bend Param V
-
Controls where the card bends in the V direction. 0 is at the center of the card, and 1 is at the edges.
- Twist
-
Rotates the card around its local normal vector. This vector is affected by Bump, Tilt U, or Tilt V.
- Tilt N
-
Magnifies how much the primitive tilts away from the surface normal by Tilt U and Tilt V. If Tilt U and Tilt V are 0, then Tilt N has no effect.
- Around N
-
Rotates the primitive orientation around the surface normal. This vector is not affected by Bump, Tilt U and Tilt V.
This has no apparent effect until the primitives are bent or tilted with Tilt U, Tilt V, Bend U, or Bend V.
- Face Camera
-
Turn on to make each card rotate so their flat side faces towards the camera as much as possible.
