$npx -y skills add arjun988/blender-skills --skill lookdevLook development loop for Blender assets combining materials, lighting, camera, and screenshot comparison until shading reads correctly via MCP.
| 1 | # Lookdev |
| 2 | |
| 3 | Material + light + camera loop. Screenshot compare. Stop when it reads. |
| 4 | |
| 5 | ## When to Use |
| 6 | |
| 7 | - Finalizing asset shading before export/portfolio |
| 8 | - Turntable / grey shader checks |
| 9 | - Matching material references |
| 10 | - Bridging `materials` and `lighting` intentionally |
| 11 | |
| 12 | ## Workflow |
| 13 | |
| 14 | ``` |
| 15 | Clay/grey pass → Base materials → Neutral light rig |
| 16 | → Beauty light → Screenshot → Gap list → Iterate (≤3–5) |
| 17 | → Optional grade → QA |
| 18 | ``` |
| 19 | |
| 20 | ## Standard Rigs |
| 21 | |
| 22 | | Rig | Use | |
| 23 | |-----|-----| |
| 24 | | Neutral 3-point | Evaluate materials fairly | |
| 25 | | HDRI studio | Product / character | |
| 26 | | In-situ scene lights | Final context | |
| 27 | |
| 28 | Keep a reusable `COL_Lookdev_Lights` + `CAM_Lookdev_*`. |
| 29 | |
| 30 | ## Checklist |
| 31 | |
| 32 | - [ ] Values read in grayscale |
| 33 | - [ ] Specular roughness believable |
| 34 | - [ ] Edges catch light (bevels/normals) |
| 35 | - [ ] Emissive under control |
| 36 | - [ ] No pure black / pure white traps unless stylized |
| 37 | - [ ] Matches reference palette if provided |
| 38 | |
| 39 | ## Iteration Rule |
| 40 | |
| 41 | Each pass: change one major variable (material OR light OR camera), then screenshot. |
| 42 | |
| 43 | ## Constraints |
| 44 | |
| 45 | ### MUST DO |
| 46 | - Grey pass before fancy textures when forms unsure |
| 47 | - Capture screenshots each iteration |
| 48 | - Hand off to `qa-review` before ship |
| 49 | |
| 50 | ### MUST NOT DO |
| 51 | - Fix modeling problems only with roughness maps |
| 52 | - Infinite tweak loops without gap list |
| 53 | |
