Build the cars that power a 3D restyling visualizer.

The job

We supply the base 3D model for each vehicle — your job is to take it and make it production-ready: separate and name the parts, fix normals, clean up the mesh, set materials correctly, and export. This isn't free-form 3D art or sourcing models: it's precise prep work where "looks fine in Blender" is not the bar. The bar is "loads clean in our engine, every part named, normals correct, textures crisp."

Models render in real time in the browser, so naming and structure must be exact — our app finds and controls each part by its mesh name. Scope is a set of passenger vehicles (final list shared on start): one production GLB plus the editable source per vehicle. We start with a single pilot vehicle, approved, before the full batch.

1 · Mesh naming scheme

Anything not on this list keeps its own name and is treated as static body/trim. Case doesn't matter; Blender's .001 duplicate suffixes are ignored.

2 · Glass — we tint it at runtime

• Single-surface panes, never solid/thickness blocks. (Solid glass renders a doubled "ghost" of the cabin through the tint.)
• Normals face outward (away from the cabin), consistently. The tint only renders on the outward face.
• No transmission / refraction on window glass — our tint is opacity-based; transmission shows the cabin straight through dark tint. (Transmission is fine on light-lens glass.)
• Smooth-shaded, with enough density on curved panes that reflections don't facet. One mesh per tint zone.

3 · Lights — the #1 failure area

• ONE light unit per corner — never two stacked assemblies. Do not leave an original lamp under a new one; overlapping lights z-fight and render half-lit.
• OFF look (HL1/TL1): dark, no emission.
• ON look (HL2/TL2): every glowing element lives here — bars, LED signatures, dotted/perforated patterns — all emissive.
• Only the ON mesh emits. No always-on emissive parts, badges, or decals — the light must go fully dark in the OFF mesh.
• Dotted/perforated LED patterns painted into a texture glow by feeding that texture (correct polarity) into Emission, tinted to the lamp color — not a separate floating decal that stays lit.
• HG/TG = the clear outer lens (we smoke-tint these); no emission. Both sides identical.

4 · PPF film layers

• One complete film mesh per package (PF/FF/TP/FB), each covering exactly that package's panels.
• Deliver them hidden / non-visible by default — we reveal the selected one. Don't leave them overlapping the paint.

5 · Materials

• Principled BSDF only. No Mix-Shader / Cycles-only / "chrome-white" node setups — they export to glTF as featureless white blobs.
• Correct PBR: paint = dielectric car paint (clearcoat ok), chrome = metallic, glass = dielectric. No baked lighting/shadows in the albedo.

6 · Textures

• 2K (2048px) minimum on body paint, interior, and any close-viewed detail. 512px maps read muddy and cheap and are not acceptable for hero parts.
• Real PBR map sets (albedo / normal / roughness / metallic). No upscaled fakes.
• Pack all textures into the file. We handle final web compression — deliver clean source-res maps.

7 · Geometry & quality

• Clean topology; no faceting on curved/glossy panels (smooth shading; sharp edges only where physically real).
• Outward, consistent normals on all visible surfaces (we render single-sided — inward faces vanish and you see through the car).
• No leftover construction geometry — delete helper objects (curves, lines, spheres, stray planes), shadow planes, and unused meshes.
• Full-detail desktop model is fine (aim under ~1.5M triangles). Applied transforms (scale 1, rotation 0), real-world scale (~4.5–5.5 m), Y-up on export.

8 · Deliverables (per vehicle)

9 · Acceptance criteria

• All parts named per scheme; _l/_r correct.
• Glass: single-surface, outward normals, no transmission, smooth.
• Lights: one unit per corner; OFF mesh fully dark; ON mesh emits all lit elements; no always-on emissive; both sides identical.
• PPF: four film meshes, correct coverage, hidden by default.
• Materials: Principled BSDF only; no white-blob exports.
• Textures: 2K+ on body/interior/detail; real PBR maps; packed.
• No faceting; clean outward normals; no construction debris.
• Applied transforms; correct scale & orientation.
• Test GLB opens and renders correctly.

10 · Process & how to apply

Pilot first. One agreed vehicle, built to this full spec and approved, before the batch. Revisions are included until the acceptance checklist passes. We supply this brief plus a reference accepted model — ask questions up front.

To apply, send: your portfolio (vehicle / hard-surface work), your rate per vehicle, and confirmation you've read this brief and can hit the acceptance checklist. Mention any experience exporting clean glTF/GLB for the web.
