You can give your character a lower body based on one of the templates within the iClone application. You can then customize the lower body if you like.
To change your character's lower body:
1. Open
either a project you have created yourself, or one of the existing template
projects. Do this by clicking the project 
button and double clicking one of the projects
in the file manager pane. If you saved a project after reading the previous
tutorial, use that project. Remember, your custom projects are in the custom
tab, and the predefined template projects are in the template tab.
2. When
the project has loaded, either click the character 
icon and the lower body 
button; or click the lower option in the drop down menu.
3. From the Template tab in the file manager pane, double-click a lower body to use for your character. Select the Sport body.
The lower body you selected is applied to your character. If you want to adjust your new lower body, select the Modify tab.
You can adjust the brightness, contrast, hue, and saturation of the lower body you selected. You can also launch an external texture editor if required. If you like the result, you may want to add your new lower body to the list of custom lower bodies.
Click the add 
button to add it to the Custom
tab.
