Introduction

What Look Dev Artists Do

Look dev artists own the visual truth of assets. They author and validate materials/shaders, texture responses, and render behaviors so characters, props, and environments remain consistent across shots, sequences, and lighting conditions. Typical outputs include:

• Physically plausible materials (skin, hair/fur, fabric, glass/volumes, metals, painted surfaces).
• Reusable material presets and look files with documented controls.
• Turntables and look bibles (reference pages that lock expectations for supervisors and downstream teams).

Pro tip: Fix shader issues (energy conservation, IOR, roughness ranges) early—tiny errors multiply at lighting/comp and cost time.

Who They Work With

• Texturing for consistent map authoring (albedo, roughness, metalness, spec, SSS weights, displacement/normal).
• Lighting/TDs to ensure assets hold up in show lighting and render efficiently.
• Groom/Creature TDs for skin/fur SSS, anisotropy, and hair lobes.
• Compositing to design AOVs/passes that enable fast shot-level control.
• CG/VFX Supervisors for sign-off against art direction and on-set reference.

Pipeline & Methodology

1. Reference & Targets: Mood boards, calibrated photography, on-set charts/spheres, scan data.
2. Neutral Look Dev: Validate in a controlled rig (see below) before creative lighting.
3. Material Authoring: Build layered BRDFs (base/coat, sheen, SSS, transmission); minimize node bloat.
4. Validation: HDRI sweeps, key/fill/rim setups, angle-of-incidence tests, distance tests, exposure brackets.
5. Packaging: Publish look files, presets, and a QC sheet; define AOVs and color pipeline (ACES/OCIO).
6. Rollout: Sequence keys with Lighting; comp slapcomps confirm relightability.

PBR & Neutral Lighting (Industry Backbone)

• PBR maps: albedo (no baked lighting), roughness, metalness (binary/near-binary), normal/displacement, SSS weights/radius, coat/spec tints.
• Neutral rig: 18% grey ground; grey/chrome spheres; key/fill/rim at fixed ratios; linear/ACES pipeline.
• Tests: Fresnel response, micro-roughness breakup, IOR ranges, hue shift under exposure, SSS depth vs. scale.

HDRI Validation & QC

Test assets under multiple calibrated HDRIs (interior, overcast, golden hour, night). Dual-view comparisons (linear vs. tone-mapped) reveal highlight clipping and color rolloff issues.

• QC checklist: energy conservation, plausible spec lobes, displacement scale, texel density, UDIM hygiene, tangent basis, AO use (for stylization only), node efficiency, AOV completeness (beauty/diffuse/spec/coat/SSS/transmission/emission, cryptomatte, Z).
• Turntables: orthographic + three-point + HDRI; label settings, units, and color space.

Tools & Tech Stack

• DCC: Maya, Houdini, 3ds Max; Katana for large-scale look dev and template publishing.
• Texturing: Substance 3D Painter/Designer, Mari (hi-res UDIMs), Photoshop for paint/scan cleanup.
• Renderers (offline): Arnold (generalist film), V-Ray (arch/env speed), RenderMan (feature film), Redshift (GPU iteration).
• Games/Realtime: Unreal Engine (Material Editor), Unity (Shader Graph/HDRP), HLSL/GLSL where needed.
• Color: ACES/OCIO; LUTs for show intent; monitor calibration.
• Groom/Skin: XGen/Yeti/Ornatrix; SSS presets for thin/thick tissues; dual-lobe spec for skin.

Film vs. Games: What Changes

• Film (offline): highest fidelity; displacement/SSS heavy; long renders; complex AOVs; strict ACES.
• Games (realtime): performance budgets; optimized shading (tiling, trim sheets, VT); LOD/material variants; platform consistency (tone mapping, exposure, MikkT tangents).
• Stylization: film may blend stylized PBR (e.g., anisotropy/sheens); games lean on post/lighting to unify art direction.

Career & Compensation

• Path: Texture/Shader Artist → Look Dev Artist → Senior/Sequence Lead → Look Dev/Lighting Supervisor → CG/VFX Supervisor.
• Comp: ~US$63k–$117k+ (region/studio dependent); realtime specialization and hair/skin expertise often command premiums.
• Growth: branch into lighting supervision, grooming/skin specialization, or realtime material lead (Unreal/Unity).
