When the head rotates, the SCM shifts so the line between its start and end points forms a 90° angle against the horizontal plane. It's important for artists to understand this anatomy when designing or animating their characters. #anatomy #3dmodeling #characterdesign

The scalene muscles are three pairs of muscles on each side of your neck. They run from your neck vertebrae down to your first two ribs. These muscles help move your head and neck – tilting, turning, and bending it forward. #anatomy #3dmodeling #characterdesign

The palm is shaped like a doughnut. This shape comes mainly from three large fat pads – thenar, hypothenar, and interdigital – forming a ring around a small, fat-free triangle in the center. #anatomy #characterdesign #3dart #sculpting

When you bend your finger, the top stays angular while the bottom becomes rounded. That’s because the top is shaped by bone, while the underside is padded with soft fat. That contrast is key for sculpting realistic hand gestures. #anatomy #3dmodeling #characterdesign

We’re finally doing it – A4S video tutorials are here! Our new free Sculpting the Head course just launched on YouTube. Start from a sphere and follow Uldis step by step to sculpt a realistic head. New videos drop twice a week – subscribe and sculpt along: youtu.be/HB1G8gXfdxU?si…

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

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

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

3D REF January update: 5 new 3D models and 3 image references! We published models used in our Sculpting the Head video tutorials: male head 2nd-level block-out, ecorche, and realistic skin. Browse these and more on 3D REF: ref.anatomy4sculptors.com #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! youtu.be/i97e-VnJxUM?si… #anatomy #characterdesign #3dmodeling

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! #3dmodeling #characterdesign

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?si… #anatomy #3dmodeling #characterdesign

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 eye area is delicate and complex, but rough shaping makes later detailing much easier. Focus on using straight lines to organize the visible shapes. Full video: youtu.be/wXZoZYkEWIQ #anatomy #sculpting #digitalsculpting

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

Uldis structures the lips by marking the vermilion border, building volume, and defining the main planes. Watch the full tutorial on YouTube: youtube.com/watch?v=5zAJLG… #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
