Torso

There are three control points on the torso that appear as squares instead of circles. They correspond to the chest, the waist, and the pelvis.

Dragging the chest control point

Dragging on the chest control point (the top one of the three torso control points) allows you to bend the whole upper torso at once. You can bend forward and backward, or sideways.

Rotating the chest control point

You can rotate the chest control point in two directions (for how to rotate a joint, see our Two ways of posing tutorial):

• Bending forward and backward: This allows you to achieve poses like "hunching back" or "pushing out chest".
• Bending sideways: This allows you to bend only the upper part of the spine while keeping the waist static. While this is possible to do in the app, it is not a very natural pose! We highly suggest that you first drag the chest control point to bend the upper body as a whole, then use rotate for any extra bending if necessary.

Dragging the waist control point

Dragging on the waist control point allows you to bend the whole spine at the waist, plus tilting the shoulder and pelvis all in one go! We designed it this way so that you can achieve a natural looking pose quickly without too much manual tuning. Let's watch the waist control point in action:

Rotating the waist control point

Rotating the waist control point works just like how you can move your own waist. You can bend forward and backwards from your waist, bend sideways, and twist around.

Tip: Rotating the waist control forward/backward and sideways is the same as dragging the chest control. Try that yourself and you will find out!

Dragging the pelvis control point

The pelvis control point controls the center of the mass of the character and allows you to make some really big adjustments to the pose! Dragging on the pelvis control point moves the location of the pelvis, and the upper body and the legs move along with it.

Rotating the pelvis control point

Since the pelvis itself does not rotate, rotating the pelvis joint actually rotates the two hip joints right next to it, and the upper body will move along:

Tips for tricky poses involving the torso

Here are some tricky poses involving the torso that people usually get wrong. If you already know human anatomy through and through, feel free to skip this section!

The "bridge" pose

Many people think that they only need to bend the character's waist to achieve the bridge pose. If you only bend the character's waist, this is what you would get:

This certainly looks wrong! So how should we fix it? Now look at the reference picture of the real woman above again, or do the pose yourself (if you are ultra flexible :P), the big bend of the "bridge" really comes from your hip, not your waist. In a bridge pose, your torso is more horizontal than vertical, like in a lying down pose. To make the bridge pose correctly, first rotate the pelvis control point to the following position:

Then drag on the ankle and wrist joints to move the legs and arms to the right location. (We will cover how to pose legs and arms in legs and arms tutorial):

Humans can typically bend their waists forward by 40-60° and bend backwards by 20-35°. Therefore, if you are bending a lot backwards like in a bridge pose, or bending a lot forward to reach your toes, you are also greatly engaging your hips besides your waist. Knowing the range of motion for different joints will help you make and draw natural looking poses.
