Study Notes

Introduction

The video focuses on sculpting minute details for skin in ZBrush.
Two main approaches for adding microscopic details exist: texturing or sculpting.
Sculpting incorporates details into textures.
The creator prefers sculpting for a handcrafted look over photorealism.
The artist's interpretation adds value, like in portrait painting, even with readily available photos.
Photo-scanning is a common studio practice for high-quality results, especially when time is a factor.

Inspiration & Techniques

Inspiration comes from Kris Costa, a renowned ILM artist.
Costa's work displays hand-sculpted details achieving near-photorealism.
References are crucial, including Pinterest and Glauco Longhi's skin details.
Daniel Boschung's website offers high-resolution face photos for various ages, aiding in wrinkles and pore reference.

ZBrush Workflow & Tools

Custom ZBrush brushes are used for skin details.
A tileable texture with pores and wrinkles is applied to the entire head using ZBrush Surface Noise.
Adjusting scale and intensity of the texture depends on age and gender.
Morph Targets store detail stages, offering flexibility and easy adjustment/undoing.
Default ZBrush brushes include:
- Spray Brush: for organic patterns/fine detail.
- Pores Brush: for pore-like detail.
- Fine Wrinkles Brush: for delicate wrinkles/lines.
- Thin Lines Brush: for subtle wrinkle emphasis.
- Clay Brush: for smoothing surface irregularities.
- Elastic Brush: for form sculpting while maintaining detail.

HD Geometry Workflow in ZBrush

The HD Geometry workflow in ZBrush creates high-resolution detail.
Base mesh subdividing increases polygon count significantly (up to 102 million).
A tileable texture using Surface Noise allows precise pore/wrinkle placement.
Morph Targets are vital for preserving detail stages in HD Geometry (each subdivision is a new mesh).
Sculpting in HD Geometry necessitates adjusting camera settings for accurate previewing.

Sculpting Specific Areas of the face

Specific facial areas are sculpted:
- Nose: A less dense pore pattern with bumps/bumps for blocked pores (blackheads).
- Lips: Wrinkles/creases along lip edges; varying shape/depth.
- Eyes: Fine wrinkles/lines around eyes, emphasizing movement/skin compression.
- Body: Applying similar techniques to the body based on area/skin type.

Breaking Symmetry & Adding Organic Detail

Breaking symmetry at final stages creates realism.
Techniques include:
- Slight rotation of the nose and ears.
- Adjusting lip and eye position.
- Shifting overall facial balance.
Variation in brush size, pressure, and alpha values, alongside considering wrinkle direction based on facial movements, is emphasized.

Exporting & Rendering

High-resolution maps (including HD Geometry) are exported from ZBrush.
Displacement and Normal maps are vital for rendering in programs like Arnold, Blender, and Marmoset.
A high-resolution Normal map in Marmoset boosts rendering realism.
