Visual Style Guide
Reference for consistent visual style across procedurally generated assets. **Triggers:** "visual style", "art style", "color palette", "material", "PBR". **Before generating:** Check `.studio/visual-style.md` for project style. **Load references when:** - Style tokens → `references/style-tokens.md` - Color palettes → `references/color-palettes.md` - PBR materials → `references/material-database.md` - Metal materials → `references/materials-metals.md` - Natural materials → `references/materials-natural.md` - Generation recipes → `references/generation-recipes.md` - Quality assessment → `references/quality-heuristics.md`

Visual Style Guide
Maintain consistent visual style across procedurally generated assets through style tokens, color palettes, and material definitions.
Core Concepts
| Concept | Purpose | Reference |
|---|---|---|
| Style Token | Modifies generation parameters (roughness, saturation, detail) | style-tokens.md |
| Color Palette | HSL ranges for consistent colors | color-palettes.md |
| Material | PBR parameters for surfaces | material-database.md |
| Recipe | Bundles token + palette + material + constraints | generation-recipes.md |
Style Token Quick Reference
| Token | Roughness | Saturation | Detail | Use For |
|---|---|---|---|---|
| RUSTIC | +0.3 | 0.7x | Medium | Medieval, weathered |
| PRISTINE | -0.2 | 1.0x | High | Sci-fi, clean |
| CYBERPUNK | -0.1 | 1.3x | Extreme | Neon, tech |
| GOTHIC | +0.2 | 0.6x | High | Horror, ornate |
| ORGANIC | +0.1 | 0.9x | High | Natural, living |
See references/style-tokens.md for 15+ tokens with full parameters.
Color Palette Quick Reference
| Palette | Hue Range | Saturation | Use For |
|---|---|---|---|
| WarmEarthy | 15-45 (orange-brown) | 0.3-0.6 | Wood, leather |
| CoolMetal | 200-240 (blue-gray) | 0.1-0.3 | Steel, chrome |
| Neon | 280-320, 160-200 | 0.8-1.0 | Cyberpunk |
| Muted | Any | 0.1-0.3 | Stone, worn |
| Vibrant | Any | 0.7-1.0 | Fantasy, cartoon |
See references/color-palettes.md for 12 palettes with specifications.
Material Quick Reference
Use dot notation: category.variant
| Category | Variants | Key Properties |
|---|---|---|
| metal | polished, brushed, rusted, chrome | High metallic |
| wood | fresh, weathered, painted, charred | Low metallic, high roughness |
| stone | polished, rough, mossy, marble | Varied roughness |
| fabric | cotton, silk, leather, velvet | Medium roughness |
| crystal | clear, colored, magical | Low roughness, optional emission |
See references/material-database.md for 40+ materials with PBR values.
Semantic Description Examples
| Natural Language | Style Translation |
|---|---|
| "rusty old barrel" | Style: Rustic, Material: metal.rusted |
| "glowing crystal" | Style: Fantasy, Material: crystal.magical, Emission: 0.8 |
| "clean sci-fi panel" | Style: Pristine, Material: metal.brushed |
| "neon cyberpunk sign" | Style: Cyberpunk, Material: tech.hologram |
Creative Workflow
1. DESCRIBE → "weathered medieval barrel"
2. INTERPRET → Style: Rustic, Palette: WarmEarthy, Material: wood.weathered
3. GENERATE → Produce mesh + textures
4. ASSESS → Run quality heuristics
5. ITERATE → Adjust based on feedback
Quality Heuristics Summary
Texture:
- Contrast > 0.15
- Noise coherence > 0.4
- Histogram balance > 0.3
Mesh:
- Triangle count within budget
- Degenerate triangles = 0
- UV coverage > 0.95
See references/quality-heuristics.md for measurement code.
Game Type Recommendations
| Game Type | Recipe |
|---|---|
| Medieval RPG | Rustic + WarmEarthy + wood/stone |
| Sci-Fi | Pristine + CoolMetal + metal/tech |
| Horror | Gothic + Muted + stone/organic |
| Cartoon | Stylized + Vibrant + any |
| Cyberpunk | Cyberpunk + Neon + metal/tech |
See references/generation-recipes.md for complete recipe code.
