Shade 10 Hair Salon
From ShadeCamp
Hair Salon makes it possible to create realistic hair. By editing guide hairs that define the way the hair looks, it is remarkably easy to create and style hair quickly. Hair Salon is available in Shade Standard and Professional.
Creating Guide Hairs
Creating Guide Hairs is the first step in the process of designing and styling hair. Guide hairs can be added and edited in the Hair Settings window.
Opening the Hair Settings Window
1. Using the Create tool create a sphere or other simple object.
2. With the sphere selected, choose Create > Hair Salon > Generate Hair. The Hair Settings window opens, allowing you to begin creating guide hairs.
Generating Guide Hairs
1. In the Hair Settings window, click the Grow button.
In the Hair Length textbox enter a value (in millimeters) for the length of hair you wish to grow.
2. In the Hair Settings preview window, click and drag in the area on the object you wish to populate with hair. Guide hairs are created where you clicked and dragged the cursor.
Note: If the object has polygon faces flipped inside out, the polygon will appear black in the preview pane and the guide hairs will be generated on the inside of the object.
Clipping Guide Hairs
1. Here we will remove some guide hairs. First choose the Rotate tool.
Click and drag in the preview window so that you are viewing the hair from the side.
2. Click the Clippers tool.
In the preview pane, click and drag across the guide hairs to thin them out.
Cutting Guide Hairs
1. Click the Cut button.
2. Click and drag across the guide hairs to chop them off.
Settings for the Cut tool can be modified in the Cut group in the lower right corner of the Hair Settings window. For more information on the tool settings, see “Cut Tool Settings.“
If not all the guide hairs are cut cleanly, you can use the Rotate tool to rotate the view and then cut again.
Matching the Length of Guide Hairs
1. Click the Match Length button.
2. Click and drag across the guide hairs as shown below to make all the guide hairs the same length.
Settings for the Match Length tool can be modified in the Match Length group in the lower right corner of the Hair Settings window. For more information on the tool settings, see “Match Length Tool Setttings.“ If not all the guide hairs are made an even length, you can use the Rotate tool to rotate the view and then use the Match Length tool again.
Lengthening Guide Hairs
1. Click the Lengthen button.
2. Click and drag from the object outward in the direction you wish to lengthen the hair.
You will probably need to repeat this click and drag operation several times for longer lengths. Settings for the Lengthen tool can be modified in the Lengthen group in the lower right corner of the Hair Settings window. For more information on the tool settings, see “Lengthen Tool Settings.“
If not all the guide hairs are lengthened to your liking, try rotating the preview using the Rotate tool and using the Lengthen tool again.
Curling Guide Hairs
1. Click the Curl tool.
2. Click and drag in a back and forth motion perpendicular to the guide hairs.
Settings for the Curl tool can be modified in the Curl group in the lower right corner of the Hair Settings window. For more information on the tool settings, see “Curl Tool Setttings.“
If not all the guide hairs have enough curl, try rotating the preview using the Rotate tool and using the Curl tool again.
Arranging Guide Hairs
1. Click the Arrange tool.
2. Click and drag over the guide hairs in the direction you wish to arrange them.
You will probably need to repeat this click and drag operation several times in order to arrange the hair to your liking.
Settings for the Arrange tool can be modified in the Arrange group in the lower right corner of the Hair Settings window. For more information on the tool settings, see “Arrange Tool Settings.“
If not all guide hairs are arranged to your liking, try rotating the preview using the Rotate view and using the Arrange tool again.
Generating Guide Hairs
After you have finished arranging the guide hairs, click OK in the Hair Settings window to create the guide hairs in the Figure window.
A Hair part is created in the Browser which contains all the guide hair objects, and the guide hairs appears in the Figure window. Render the scene to see what the hair actually looks like.
To modify the guide hairs, select the guide hairs you wish to modify and select Hair Attribute Setting from the Custom tool.
Hair Texture Settings
Applying Texture to Hair
1. With the Hair part selected, choose Hair Texture Settings from the Custom tool. The Hair Texture Settings dialog appears.
2. Here we will change the Density to 0.2.
Next, click somewhere in the middle of the gradation bar on the left side of the dialog to create a new arrow marker.
With this new arrow marker selected, click on the color box below to change the color. Here we will choose a brown.
3. Click OK to close the dialog and apply the settings.
Now open the Surface window. The texture you just specified should be applied to the hair.
The surface attributes are also saved as images and a Master Surface.
Render the scene to view your results.
Note: If the hair does not render correctly using Ray Tracing or Path Tracing rendering methods, try setting the Ray cast level to 5 or greater in the Misc. tab of the Rendering Settings. For more information on the Ray cast level, see “ “ In the User Guide.
To modify a hair texture choose Hair Texture Settings from the Custom tool or from the mapping Info menu in the Surface window.
Applying Texture to Individual Guide Hairs
Multiple textures can be applied to different guide hairs.
1. With the Hair part selected, choose Hair Salon > Generate Hair Texture from the Create tool. Adjust the settings to your liking and click OK to create the texture.
2. Repeat the above steps to create a second texture.
3. Open the Hair Settings window by choosing Hair Settings from the Custom tool. Select the Paintbrush tool at the top left of the window.
4. At the bottom of the Color Settings group is a list of the textures you have created for this hair part. First select the one you wish to use, then click the polygons in the preview window to apply the selected texture to those guide hairs.
Creating a Polygon Mesh from Guide Hairs
Guide hairs can be edited like any other polygon mesh if you first convert them to a polygon mesh. With the hair part selected in the Browser, choose Hair Salon > Create Hair from the Create tool.
To make fine adjustments to the hair it is usually best to style the guide hairs as close as possible to the desired result and then convert them to polygon meshes and edit the individual polygons.
Note: If you wish to use render hair using ShadeGrid, first convert the guide hairs to polygon meshes for optimal results.

Hair Settings Window Shortcut Keys
About Surface Attributes of the Hair Part
The attributes of the generated hair and the hair texture images are stored in the surface attributes of the Hair part.
This information is used when rendering or when creating a polygon mesh from guide hairs, except that the Transparency is always set to 1.0 and the Backlight to 0.5.
A mapping layer is added to the surface attributes when a new hair texture is created.
At this time the attributes are stored in the order of “Image/Diffuse”, “Image/Transparency”, “Image/ Bump”. These three values together express the hair texture. By storing the values in this order, images not automatically created by Hair Salon can be used as hair textures. |
