Before starting this tutorial, let's look at the current level of skeleton, in this case, the pelvic bone of the Tyrannosaurus rex is the highest level of the skeletal hierarchy, which is the parent skeleton of all bones.
After determining the level of the skeleton, we first use the Joint tool tool to build the pelvic bone. Create a new layer named Bone, and then label it a different color. Confirm that the bone layer is selected, switch to the animation module, select the top menu-> skeleton-> Joint or select the Tool Line tool Joint tool.
When the mouse pointer changes to "+", click on the position of the pelvis to build joint, click on a few to build a tail of the skeleton. Press the ENTER key to complete.
4. Open the Hypergraph Super chart, look at the established joints, select the first joint to rename to Pelvis.pelvis it is the top of the entire hierarchy list.
5. Press the Y key to return to the previous tool, starting from the pelvic bone pelvis to establish joint to the head, note in the correct position of the neck joint, before establishing the IK handle, can adjust the position of each joint.
