🧵 Anatomy for 3D Artists – The Essential Guide to CG Character Success

1/6 Most 3D models look “off” because of skeletal mistakes, not skin details. Learn the bony landmarks first – clavicle rotation alone fixes shoulder deformation.

2/6 Muscle groups are just modified primitive shapes. See the trapezius as a kite, the deltoid as a teardrop. Sculpt forms, not wrinkles.

3/6 Topology = anatomy in wireform. Edge loops must follow muscle direction – especially around the eyes, mouth, and knee. Anatomy For 3d Artists The Essential Guide For Cg

4/6 Proportions cheat:
– Elbows = bottom of ribcage
– Wrists = crotch level
– Fingertips = mid-thigh

5/6 Age changes everything. Children have no visible clavicles, elderly have hollowed temples and prominent sternum.

6/6 Start with an écorché sculpt. No skin until muscles are believable. Retopologize, then rig. Your deformations will thank you.

Group muscles by function and visual effect; focus on silhouettes and how muscles change with pose.

Modeling tip: treat muscle groups as volumes that compress, stretch, and slide over bones.

Skinning tip: use dual-quaternions for volume preservation; add corrective blendshapes for muscle bulges. 🧵 Anatomy for 3D Artists – The Essential
