Bones

Other bones will have various default parameters depending on their degrees of freedom and parameter names assigned by the content creator. DAZ uses a standard convention for naming parameters based on their function. Some of the possible parameters are:

  • Bend: The Bend parameter rotates the selected bone about its own lateral axis, that is, the local axis that passes through the parent joint from left to right.
  • Side-Side: The Side-Side parameter rotates the selected bone toward or away from the figure’s centerline. In other words, the rotation occurs along the bone’s own transverse axis, that is, the local axis that passes through the parent joint from front to back.
  • Front-Back: The Front-Back parameter rotates the selected bone toward the figure’s anterior (front) or posterior (back) sides. For an example, hold your arm straight out and rotate your shoulder forward and back.
  • Twist: The Twist parameter rotates the selected bone about its own longitudinal axis, that is, the local axis that extends from parent joint to child joint.

Note graphic NOTE! The terms transverse, lateral, longitudinal, anterior, and posterior refer only to common medical terminology, which is the basis for naming the above-listed types of rotation. They do not relate to the Cartesian axes (X,Y,Z) or global & local coordinates.

Note graphic NOTE! In the above image, notice that a human elbow cannot bend along its transverse axis. If you select the forearm on a DAZ figure, you will see that you cannot bend the arm in this manner.

Hip Type

Some DAZ and third-party content supports geometry swapping, where you can substitute one type of geometry for another. If you have content that supports this feature (such as DAZ’s Michael 2 figure), a Hip Type drop-down menu appears in the Parameters tab when you select an object or bone that contains this feature. Geometry swapping is typically used with nude male figures to enable or disable displaying the male genitalia. This menu lists all of your available options (such as Hip and Genitals Off for a nude male hip bone). Click the menu and make your selection to enable your desired option.

Multiple Bones

DAZ Studio lets you work with more than one bone at a time. Once you have made your selection, you can modify any parameter shared by all selected bones using the Parameters tab. Here is one example that shows you how to make a fist using multiple selected bones. The figure below shows the selected bones and initial Bend setting. (Notice that it will likely say <Multiple> at first, but you can change this to 0.00 without affecting joint movement.)

We applied 30 degrees of bend to all of the selected bones in the hand. The figure below shows the results of that action. In just a few seconds, we created a hand pose that can be refined into a grasp or fist depending on your needs. The results are approximate, but positioning multiple bones can save you quite a bit of time as opposed to setting each bone’s joint into place.
