The Hair Light Attr(ibutes) rollout lets you adjust properties for the hair shadow map generated by the light. This rollout appears for supported lights at render time. If you want to adjust a light's hair settings before render time, you can display it explicitly by following the steps shown in the path annotations at the beginning of this topic.
-
Create a supported light. > Select an object with the Hair And Fur modifier applied. > Render Settings > Effects panel > In a viewport, select the light. > Hair And Fur rollout > Lighting group > Click Add Hair Properties. >
Modify panel > Hair Light Attr rollout
-
Add a supported light and an object with the Hair And Fur modifier applied. > Rendering menu > Effects > Highlight the Hair And Fur render effect. > Hair And Fur rollout > Lighting group > Select the light (in a viewport). > Click Add Hair Properties. > Modify panel > Hair Light Attr rollout
You specify which lights to use in the Hair And Fur render effect. By default, Use All Lights At Render Time is on, so all supported lights in the scene can illuminate hair. Use this rollout to set hair-specific shadow-map values. Hair shadows ignore the light's ordinary shadow-map settings (for other 3ds Max objects).
Interface
- Light hair
-
When on, the light can illuminate and cast shadows from the hair.
Note: The light must also be set to cast shadows (General Parameters rollout
Shadows On). - Resolution
-
Sets the size (in pixels squared) of the shadow map that's computed for the light.
The shadow map size specifies the amount of subdivisions for the map. The higher the value, the more detailed the map will be, but the more memory is required.
- Fuzz
-
Sets the softness of the shadow edges. See Sample Range.
Left: Fuzz=0.0
Center: Fuzz=5.0
Right: Fuzz=10.0
The arrow points to the shadow cast by the hair on the underlying surface.
