Week Ⅰ – Introduction to ZBrush

This week we were introduced to ZBrush, as well as the in-depth anatomy of the human skull. We were taught about the differences between female and male skulls, and all the most visible features to look for in a human face.

 

Zbrush Shortcuts:

• B – brush menu
• S – brush scale
• F + shift – wireframe

 

symmetry shortcut: x

shift d down with resolution

d go up with resolution

ctrl d add another layer of subdivision

shift + control > trim rect = cutting brush

 

Dynamesh: allows you to have a dynamic resolution where you actually need it

click control and drag to subdivide areas that need it most

 

dynamesh is not a replacement of subdiving its a starting point

geometry > modify topology >

adding another object = subtool > append

Masking – can’t touch the area that is currently masked

ctrl

 

 

Adding reference images to the viewport:

texture > import > choose your reference image

brush > samples > spotlight projection off (otherwise the tools won’t work properly!)

z = set opasity

shift + z = toggle the reference image visibility

Visibility tools:

Visibility tools help hide certain elements of the mesh.

 

ctrl shift – trim rect tool > ctrl + shift + n

ctrl shift and click to get everything back

 

splitting off one subtool into 2 different ones:

ctrl + w (masking everything that is currently visible)

mask ctrl shift trim rect tool & ctrl + shift + n of the object you want to be split off

subtool > split > groups split

 

 

Basic ZBrush brushes:

• clay (b > c > l)

• clay buildup (b > c > b) – constantly adds volume

• clay tubes

• clay tubes constant

• dam standard (b > d > s) – wrinkles, sharp edges

• move brush (b > m > v)

• smooth brush (shift)

• standard brush (b > s > t)

• trim dynamic (b > t > d) – good for hard surface, flattens

Week Ⅱ – The Nose

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Week Ⅲ – The mouth

Brushes used for sculpting the mouth:

• claytubes
• smooth

Week Ⅴ – The Ear

 

Sculpting the ear:

Mask out the shape of the ear using the mask tool, inverse the mask (tapping the CTRL key on the background) and drag out the basic shape of the ear.

Week Ⅵ – The eyes

Hand in nose, mouth, ear & eye sculpts in a zipped file + upload on sketchfab by 07/11/2023.

Week Ⅶ – Villain: Comparative Anatomy

5th of January deadline of handing in the villain sculpt  eyes in  maya   good  textures  forgoodmarks

Villain Moodboard

 

Idea 1: Vampire

eyebags, elf ears, redness around the eyes, pale skin, visible cheekbones, vampire fangs, vampire bangs

 

Villain –

For my Villain project, I decided to start out with a basic poly sphere. I did that because I find it easier to first build up the underlying bone structure of the face to make sure that the overall anatomy is as accurate as possible.

creating the eye sockets

Week 7 – Villain: facial fat

 

2 types of fat

subscutaneous fat

• is all over the body
• as an individual gains weight subcutaneous fat gathers in some places more than others
• it does not collect uniformly
• it forms little compartments within this superficial layer, observable collection points

sctructural fat

• usually deeper , close to the skull
• tjjeu are either for helping bone to slide around
• or a structural to push muscles out eg. orbital fat

 

fat pads

orbital fat

• it is held back by6 orbital septum which holds back the fat

• as you age the elasticity of the orbital septum weakens and gravity influences it

• there are fat pads whose role is to protect and package the eye

• there are two up top and 3 on the bottom

• when young they blend into one and softly protect the eye

• as ageing occcurs the orbital septum relaxes

SOOF Fat – sub-orbicularis oculi fat

• ageing affects the elasticity the fat sinks down a wrinkle can develop and a bulge

 

Buccal Fat

• is a deep fat pad located on either side of the face between the buccinator muscle and several more superficial muscles it can give you chubby cheeks

• once it is removed or fades it  does not return

Malar Fat

 

Sub-mental Fat

Jowl Fat

a particular place; the middle third

it does not happen in the surrounding areas

 

 

 

when sculpting

how far apart eyes are

how wide eyes are

nose measurents witdth

mouth width

fat pads

ZBrush texturing

 

eye, nose, lips, neck, ears, more red

skull, centre of nose, cartilage of the ear – more yellow

chin area, neck – more gray/blue

bringing the model into maya

 

creating UV maps

Subdivision level to 1

ZPlugin > UV master > Unwrap

 

exporting the texture

Subdivision level to normal

ZPlugin > Multi Map Exporter > Texture from PolyPaint > Create All Maps

 

veins > spray > drag rect > alpha > alpha 60 65 intensity

aistandardsurface

preset to skin

subsurface > pick the uv map texture

 

prject map onto image

texture > import > select the texture > select texure in zbrush > add to spotlight > middle o move > line up with the 3D model > adjust opacity > brush > freehand > alpha > none or alpha 01 > ZAdd off > RGB On > basic material > light ? > to get rid of the circle press z > paint on the 3D model > shift Z

 

Week 9 – Neck

Boney Landmarks ”something that’s always visible”

Clavicle

The clavicle or collarbone is a long

Prominent whether muscular or not

 

7th cervical vertebral bone

a useful landmark on the upper back between the trapezius muscle

 

muscles

sternocleidomastoid

the primary actions of the muscle are rotation of the head to the opposite side and flexion of the neck

it is given the name because it oryginates at the manubrium of the sternum and the clavicle and has an isertion at the mastoid process ofthe temporal bone of the skull

attaches to clavicle

Platysma

the platsma is a superficial muscle that overlaps the sternocledomastoid

it is a broad sheet arising from the fascia covering the upper parts of the pectoralls major and deltoid its fibers cross the clavicle and proceed obliquely upwad and medially along the side3 of the neck

 

Trapezius

Traps are a diamond shaped muscle that are on the back. The 7th crevicular vertebrae is visible between them and when developed are visible from the front

Deltoid

Throat: Larynx Adams Apple

Not usually visible on women. Men have larger voice boxesand are more prominent the reason why men speak in deeper tones

During puberty, boys develop a larger larynx. This makes their voices deeper over time, and it can create the bump at the front of the throat that’s known as an Adam’s apple. Girls also undergo changes to their voice box during puberty. The degree of laryngeal growth in females isn’t as significant as in males, so most women don’t have Adam’s apples. Some women with a larger larynx do, but this indicates the size of the voice box only

 

character workflow

import the model

geometry > zremesh

zplugin > uvmaster unwrap

subdivide up to 4

export texture and displacement map

export model at 1 subdiv
