Step 2

Select all teeth meshes, go to Mesh > Separate tool to separate all teeth as shown in the following image.

Step 11

Select and rotate Head02_Jnt01 to check if all upper teeth and gum including eye balls follow or not. It looks good.

2. Skin Binding With Body Mesh

Step 1

Select the body mesh followed by Root01_Jnt01 and then go to Skin > Bind Skin and click on the option box.

Step 2

In the Bind Skin Options window, set the value of Max influences as 2 and then click on Bind Skin button to apply the Skin command.

Step 3

To check the effectiveness of skinning, rotate the thigh joint. You will see some abnormal deformations. You'll need to correct the skin weight settings to rectify the problem.

3. Applying IKs With Joints

Step 1

Go to Skeleton > Create IK Handle and click on the option box.

Step 4

Following the same way, apply IKs on both legs and hands joints and then rename these as Left_Leg_IK_handle01, Right_Leg_IK_handle01, Left_Hand_IK_handle01 and Right_Hand_IK_handle01 as shown in the following image.

4. Creating Spline IKs on Spine Joints

Step 1

Go to Skeleton > Create IK Spline Handle and click on option box. In the settings window, keep all settings by default.

Step 8

Select the cluster, go to clusterHandleShape tab, set Origin Y and Z values to shift it upward as shown in the following image.

Step 9

In this way, you have created three more clusters according to the vertices. Shift them all upward a bit.
