Creature Artist

Believable creature design grounded in anatomy. Movement-informed topology. Fantasy with physical plausibility.

When to Use

• Fantasy creatures, monsters, aliens
• Quadrupeds, flying creatures, aquatic forms
• Hybrid designs (part animal, part mechanical)
• Boss creatures, enemies, companions

Design Principles

1. **Anatomy grounding** — Even fantasy references real biology 2. **Silhouette first** — Unique readable shape 3. **Movement logic** — Skeleton supports intended motion 4. **Muscle flow** — Surface forms follow underlying structure 5. **Storytelling** — Design communicates behavior (predator/prey/scavenger)

Workflow

Reference → Skeleton Blockout → Muscle Masses → Surface Forms
    → Detail (sculpt or model) → Retopology → Rig → Animation Test

Creature Types

| Type | Skeleton Base | Key Forms | |------|---------------|-----------| | Quadruped | Dog/horse reference | Shoulder hump, haunches | | Biped | Human/primate | Upright spine, heel plant | | Flying | Bat/bird | Wing membrane, keel chest | | Aquatic | Fish/shark | Lateral line, fin placement | | Serpentine | Snake | Ribcage segmentation | | Insectoid | Arthropod | Segmented body, jointed legs |

Muscle Flow

• Origin → Insertion direction visible in surface
• Flexed areas: compressed forms, overlapping skin
• Extended areas: stretched, thinner surface
• Fat deposits: soft transitions (belly, cheeks)
• Scars/armor: break muscle flow intentionally

Bone Structure Planning

Before surface modeling: 1. Place joint locations (spine segments, limbs) 2. Verify range of motion at each joint 3. Ensure limb attachment supports gait cycle 4. Head/neck connection supports attack/look poses

Surface Detail Tiers

| Tier | Detail | Method | |------|--------|--------| | Primary | Overall mass | Blockout/sphere modeling | | Secondary | Muscle groups | Sculpt or extrusion | | Tertiary | Skin folds, veins | Sculpt | | Micro | Scales, pores, scars | Sculpt + bake to normal |

Hybrid Creatures

Mechanical + organic:

• Separate meshes: `SM_Creature_Bio`, `SM_Creature_Mech`
• Hard surface joints at organic/mechanical transition
• Rig: mechanical parts use constraints; organic uses weights

MCP Integration

1. Create skeleton blockout (armature or mesh guides) via MCP 2. Build primary masses with mirror/sphere modeling 3. Hand off to sculpting for detail pass 4. Query proportions against reference scale figure 5. Organize bio/mechanical collections separately

Constraints

MUST DO

• Reference real anatomy even for fantasy
• Test silhouette from gameplay camera angle
• Plan rig joints during blockout
• Separate hero detail from background creatures
• Retopologize before rigging

MUST NOT DO

• Design without movement consideration
• Uniform detail density (hero face/feet get more)
• Skip retopology on sculpted creatures
• Ignore polycount tier (background vs boss)
• Attach limbs without joint clearance

| Topic | Reference | Load When | |-------|-----------|-----------| | Quadruped anatomy | `references/quadruped-anatomy.md` | Four-legged creatures | | Flying creatures | `references/flying-creatures.md` | Wings, flight | | Pipeline | `../references/asset-pipeline.md` | Phase context |

Style Integration

| Style | Approach | |-------|----------| | realistic-style | Grounded anatomy; PBR skin | | stylized-style | Exaggerated features; bold shapes | | lowpoly-style | Minimal surface; texture detail | | horror-style | Uncanny proportions; exposed anatomy |
