Lookdev

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
