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

0304

Anatomy For Sculptors @anatomy4sculptors.bsky.social · 27/05/2026

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

Anatomy For Sculptors @anatomy4sculptors.bsky.social · 29/04/2026

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

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

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

Anatomy For Sculptors @anatomy4sculptors.bsky.social · 04/02/2026

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

Anatomy For Sculptors @anatomy4sculptors.bsky.social · 28/01/2026

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
