The forehead is heavily shaped by the frontal bone hidden beneath only a thin layer of soft tissue. Learn how it defines the forehead, eye socket, and root of the nose in the new Head Anatomy course with Uldis Zarins: anatomy4sculptors.com/product/head-anatomy/ #anatomy #3dmodeling #characterdesign

The head isn’t round! Knowing the bony landmarks that define the widest parts of the head and face helps keep your drawings and sculpts on track. For more practical tips, check out the new Head Anatomy course by Uldis Zarins: anatomy4sculptors.com/product/head... #3dmodeling #characterdesign

The anatomical snuffbox (yes, that's the real name) is the hollow that appears at the base of the thumb when it's extended. It's formed by these three thumb tendons. It's a small but important surface landmark if you strive to create believable hands. #anatomy #characterdesign #3dmodeling

The ulna is one of the easiest bones to track on the surface. No matter how you turn the hand, it always extends from the elbow to the little finger side of the wrist, making it a reliable bony landmark for artists. #anatomy #3dmodeling #characterdesign

Bony landmarks are much easier to understand when you can see the skeleton beneath the muscles. Compare the skeleton, transparent ecorche, and color-coded ecorche to see how the bones and muscles relate to one another in the same pose. Find all three models on 3D REF: anatomy4sculptors.com/3d-ref

Clavicle visibility depends on how developed the pectoralis major muscle is. A thicker chest has more volume over the bone and reduces its visibility, while a leaner chest leaves the clavicle more exposed under the skin. #anatomy #3dmodeling #characterdesign

The three heads of the shoulder muscle (deltoid) originate from visible bony landmarks on the clavicle and scapula. The shoulder is a complex system made of a mobile shoulder girdle and layered muscles, creating its unique form. #anatomy #characterdesign #3dmodeling

The yellow line marks a shared attachment region of the trapezius and deltoid. Both muscles attach to the same part of the clavicle, but from opposite sides – the trapezius from above and the deltoid from below. #anatomy #3dmodeling #characterdesign

The two bumps at the front of the hip are created by the sartorius and tensor fasciae latae. Both attach near the iliac crest, making it an important bony landmark of the pelvis for locating these surface forms. #anatomy #3dmodeling #characterdesign

Unlike the female butt, which is mainly shaped by fat pads, the male butt is shaped primarily by the glute muscles. This creates a more angular appearance, with the underlying muscles visible in the surface forms. #anatomy #characterdesign #3dmodeling

Female butt surface forms are shaped by the major fat pads, while the glute muscles create the underlying structure. Understanding this layering helps explain why the female butt usually appears softer and rounder than the male butt. #anatomy #3dmodeling #characterdesign

Veins and tendons are both visible on the back of the hand, but they have very different patterns. Tendons run in straight lines toward the fingers, while veins branch and meander across the surface as darker bluish forms. #anatomy #characterdesign #3dmodeling

Crossing the arms brings the shoulders forward and puts the chest and upper limbs into a compact pose. Males and females differ: female forms tend to be smoother and more uniform, while male arms show more clearly defined individual muscles. #anatomy #3dmodeling #characterdesign

Forced pronation combines regular forearm pronation with movement in the shoulder. As the deltoid drives the movement further, the elbow shifts outward and the triceps becomes prominent. #anatomy #3dmodeling #characterdesign

Observe the form change during supination, semipronation, and forced pronation, which rotates the elbow outward, engaging the shoulder's deltoid muscle. The dots mark the bony landmarks for tracking muscle attachments across all positions. #anatomy #3dmodeling #characterdesign

Supination and pronation change which muscle group is visible in the front view. In supination, the palm turns up and flexors move forward. In pronation, the palm turns down, shifting the flexors away and leaving mostly extensors visible. #anatomy #3dmodeling #characterdesign

The color-coded blockout makes it much easier to see the separate parts that make up the anatomy of this Asian female head. Without it, the forms blend together so organically that it’s hard to make sense of the structure. #anatomy #3dmodeling #characterdesign

We lose details after DynaMesh, but that’s the point. It reveals what’s too plain or too busy. Uldis restores shapes and rebuilds weaker ones. Narrow areas become contrast zones, where he adds detail with the alpha brush. #anatomy #3dmodeling #characterdesign

Hair is built in stages. It starts with the main masses, then gets divided into smaller groups, breaking up parallel lines to avoid an artificial look, and finally refined with detail. Full video on YouTube: youtu.be/mreEQYEN4GU #anatomy #3dmodeling #characterdesign

If something feels off when making the lips, you might be making them too symmetrical. They’re not. The upper and lower lips are different shapes. #anatomy #3dmodeling #characterdesign

Uldis structures the lips by marking the vermilion border, building volume, and defining the main planes. Watch the full tutorial on YouTube: www.youtube.com/watch?v=5zAJ... #anatomy #3dmodeling #characterdesign

When creating the eye, don’t focus only on the eyeball and eyelids. The forms above and below the eye play a major role in defining its final appearance. #anatomy #characterdesign #3dmodeling

A believable smile is more than just lifted mouth corners. The orbicularis oculi muscle compresses the eye area, creating the squint that makes a smile feel genuine. At the same time, several other muscles move and shape the mouth. #anatomy #characterdesign #3dmodeling

The back of the ear has two main forms – a pizza crust edge and a cone connecting to the head. Watch Uldis block out these volumes in the full video tutorial on YouTube: youtu.be/i97e-VnJxUM?... #anatomy #3dmodeling #characterdesign

Ears don’t just wrinkle with age, they grow. On average, ear length increases by about 0.22 mm per year, adding up to nearly 1 cm over 50 years. Most of this change shows in the earlobe. So if you're creating an older character, make the ears longer! #anatomy #3dmodeling #characterdesign

Starting with the contour, we define the helix and then carve into the concha. But that's just a small part of it – watch our full ear sculpting video on YouTube! www.youtube.com/@anatomy4scu... #anatomy #characterdesign #3dmodeling

Nasal aging is a structural shift – as the nasal tip descends, the cartilages separate, causing the nose to gradually increase in length and size. An important consideration when creating older characters. #anatomy #characterdesign #3dmodeling

Early eye aging is driven by decreasing orbital fat. When character designers depict this, they need to keep in mind that as volume thins, tear troughs deepen, eyebags become more pronounced, and the orbital rim becomes exposed as a bony landmark. #anatomy #3dmodeling #characterdesign

In youthful faces, superficial and deep fat is evenly distributed and held in place by facial retaining ligaments. As we age, these ligaments lose their firmness, causing the fat layers to shift and droop. This changes the structure and proportions of the face. #anatomy #3dmodeling #characterdesign

The ear is tricky to sculpt because of all its complex curves and folds. For character design, understanding its true volume and structure is key, and these 3D model cross-sections break it down slice by slice. #anatomy #3dmodeling #characterdesign
