Texture Workflow
Bake high-poly detail to efficient texture sets. Optimize memory. Engine-ready outputs.
When to Use
- Baking sculpt detail to normal maps
- Creating texture atlases for modular kits
- PBR texture set generation
- Decal placement and blending
- Texture memory optimization
Workflow
High/Low Poly Setup → Cage Setup → Bake Maps → Composite
→ Atlas Pack → Engine Format Export → Validation
Standard PBR Texture Set
| Map | Format | Notes |
|---|---|---|
| Base Color | sRGB PNG | No embedded AO |
| Normal | Linear PNG | OpenGL convention unless engine specifies |
| Roughness | Linear PNG | Single channel |
| Metallic | Linear PNG | Single channel |
| AO | Linear PNG | Multiply in shader, not base color |
| Height | Linear PNG | Optional parallax |
| Emission | sRGB PNG | Mask-based |
| ORM Packed | Linear PNG | R=AO, G=Roughness, B=Metallic (Unreal) |
Naming: T_[Asset]_[Map] per ../references/naming-conventions.md
Bake Setup
1. Low-poly mesh with UVs (active)
2. High-poly mesh (sculpt or detail) — selected
3. Cage extrusion: 0.01–0.05m (adjust per asset scale)
4. Ray distance: match cage
5. Bake margin: 16px minimum
6. Anti-aliasing: enabled
Maps to Bake
| Map | Source | Priority |
|---|---|---|
| Normal | High→Low | Required |
| AO | High or low (cavity) | Required |
| Curvature | High sculpt | Wear masks |
| Position | High | Optional (blending) |
| Thickness | Subsurface meshes | Characters |
Texture Atlas Strategy
Modular kits share one atlas:
1. All modules UV'd to shared 0–1 or UDIM space
2. Bake each module to atlas regions
3. Trim sheet areas for repeating detail
4. Single material references atlas
5. Document region map for artists
Decals
- Decal mesh projected on surface
- Separate UV channel or atlas region
- Blend via alpha mask
- Limit decal overdraw in engine
Memory Optimization
| Technique | Savings |
|---|---|
| ORM packing | 3 textures → 1 |
| Shared atlas | N materials → 1 texture |
| Lower res on hidden surfaces | 50%+ memory |
| BC compression in engine | 4:1 or 6:1 |
| Trim sheets | Reuse detail across assets |
Resolution Guidelines
See ../references/polycount-budgets.md texture section.
MCP Integration
- Setup bake objects via MCP
- Configure bake settings via MCP if supported
- Export baked images via MCP
- Assign baked textures to materials via MCP
- Query texture count and resolution
Validation Checklist
- Normal map correct orientation (test in engine)
- No UV seams visible in bake
- AO not baked into base color
- Consistent texel density in final textures
- Texture resolution within budget
- Files named per convention
- sRGB vs Linear correctly assigned
Constraints
MUST DO
- Bake high-poly detail before discarding sculpt
- Use cage for clean normal bakes
- Pack ORM for engine efficiency
- Test normal map orientation in target engine
- Document atlas regions for modular kits
MUST NOT DO
- Bake without cage on complex shapes
- Embed AO in base color (PBR standard)
- Exceed texture budget without LOD justification
- Use inconsistent normal map conventions
- Skip margin in bake settings
