Lookdev

Material + light + camera loop. Screenshot compare. Stop when it reads.

When to Use

• Finalizing asset shading before export/portfolio
• Turntable / grey shader checks
• Matching material references
• Bridging `materials` and `lighting` intentionally

Workflow

Clay/grey pass → Base materials → Neutral light rig
  → Beauty light → Screenshot → Gap list → Iterate (≤3–5)
  → Optional grade → QA

Standard Rigs

| Rig | Use | |-----|-----| | Neutral 3-point | Evaluate materials fairly | | HDRI studio | Product / character | | In-situ scene lights | Final context |

Keep a reusable `COL_Lookdev_Lights` + `CAM_Lookdev_*`.

Checklist

• [ ] Values read in grayscale
• [ ] Specular roughness believable
• [ ] Edges catch light (bevels/normals)
• [ ] Emissive under control
• [ ] No pure black / pure white traps unless stylized
• [ ] Matches reference palette if provided

Iteration Rule

Each pass: change one major variable (material OR light OR camera), then screenshot.

Constraints

MUST DO

• Grey pass before fancy textures when forms unsure
• Capture screenshots each iteration
• Hand off to `qa-review` before ship

MUST NOT DO

• Fix modeling problems only with roughness maps
• Infinite tweak loops without gap list
