53 points and precautions for human body

There are 5 points on the head: one at the highest point on the top of the head, and the other 4 points are marked in the front, back, left, and right respectively. The points on the front, back, left, and right should not be completely symmetrical, and the point on the top of the head should be offset to make it different from the other 4 points.
There are 8 points on the upper torso: 1 point at the collar (clavicle position), 1 point at the midpoint of the front centerline (sternum), 1 point at the intersection of the spine and shoulder line (neck end), 1 point at the midpoint of the back centerline at the same level as the center of the front centerline, and 1 point at the front and back of the left and right shoulders respectively.
There are 8 points on the upper body: 1 point on the collar (clavicle position), 1 point at the midpoint of the front centerline (sternum), 1 point at the intersection of the spine and shoulder line (neck end), 1 point at each midpoint of the back centerline in the same horizontal plane as the center of the front centerline, and 1 point at the front and back of the left and right shoulders.
There are 6 points at the waist: 2 at the front of the hips, 2 symmetrically at the back and front with the rear point slightly higher than the front point, and 1 on each side asymmetrically, with one slightly forward and the other slightly backward.
There are 8 points on the legs: 1 on the middle and outer sides of each thigh, with the point on the left thigh pointing upwards in the middle and the point on the right thigh pointing downwards in the middle, which is asymmetrical to the right thigh.
There are 10 points on the feet.One marker in front of the front foot, two at the bending joint of the front foot (ensuring that the inner marker is farther forward than the outer marker), one at the ankle, one at the heel, and the two markers on both sides of the front foot should be on the same plane.Maintain the same height of the attachment points on both sides of the left and right ankles and front soles as much as possible.
If there is an issue with the occlusion of the elbow joint marker, place the inner elbow joint marker slightly above the elbow joint, behind the arm, rather than inside the elbow joint.
If you encounter issues with knee marker blocking, place the inner knee marker slightly forward rather than on the inner knee.
Keep the height of the attachment points on the left and right waists, knees, and ankles as consistent as possible.
When flipping the wrist and forearm, if recognition is not possible, check and adjust the attachment points of the forearm. Each point on the left and right forearms is asymmetrical, with one point in the middle of the left forearm and one point in the middle of the right forearm, both located on the outside. Do not attach them in the middle. When attaching points in this area, the actor can bend their arms upwards and place them on their shoulders to adjust the attachment points of the forearm. The distance between the attachment point on the forearm and the inner attachment point on the wrist (WristIn) should be greater than the distance between the attachment point on the forearm and the outer attachment point on the wrist (WristOut).
Secure areas that are prone to loosening and wrinkling with straps, such as the waist, upper arms, wrists, and palms.
