The descriptionShape node contains the global settings that control the shape and display of the hairs on the mesh surface.
Primitive Attributes
- Width Scale
- Globally scales the per-CV width value to generate the final width of the hairs displayed in the scene.
The local width of each hair is determined on a per-CV basis. The
Width brush sets width values on each CV as it moves across the hairs. These width per-CV values are then multiplied by the
Width Scale
attribute. You can also set
Width Scale
in the
Create Interactive Groom Splines Options window.
- Taper
- Controls the width at the tip of each hair compared to its base. Positive values make the tip narrower than its base, and negative values make the tip wider than its base.
- Taper Start
- Controls where the hair width starts to taper. Taper Start ranges from 0.0 (the base) to 1.0 (the tip).
- Tube Shade
- Displays hairs so that they appear tubular rather than flat.
Tube Shade
only works in Viewport 2.0 and has no effect on the final render.
- Width Ramp
- Lets you set the width of hairs along their length from root to tip. Values generated by the ramp are multipliers for the set
Width Scale
attribute value. You can choose how Maya interpolates between points in the ramp by selecting a method from the Interpolation list.
Preview Settings
- Highlight Placed Splines
- When on, hairs added to the mesh surface using the
Place tool display with the selected color.
Interactive Grooming Tools.
Note: Turn this on to display the splines transferred from a legacy XGen description after it is converted to interactive groom hairs.
- Color
- Click the swatch to choose a color to display placed hairs.
- Color Intensity
- Adjusts the opacity of the set
Color.
- Draw Control Vertices
- When on, control vertices on each hair strand display as yellow points.
- CV Size
- Sets the size of the hair control vertices in pixels.
- CV Opacity
- Adjusts the opacity values of the control vertices' display.
- Render Density Multiplier
- Lets you increase or decrease the density of the hairs for rendering. This changes the density of the hairs at render time only. The resulting hair density does not appear in scene view.
