Premium 3D Car Seat Configurator Assets

About the project I'm building a web configurator (React, Three.js, React Three Fiber) where customers choose a car seat‑cover design and then recolour every upholstery panel, piping run, stripe and stitch group in real time, on desktop and mid‑range phones. I need an experienced 3D artist to create the seat models and seven cover designs. This is 3D asset creation only; the configurator code is handled on my side. The work is in two stages: a paid prototype of one seat, then the full set once the prototype is approved. Stage 1: ADI driver‑seat prototype A generic front driver seat for a right‑hand‑drive market, delivered as two layers: a plain base (seat form, side trims, recliner lever and pivot, slider rails and feet, headrest posts) and the ADI cover that loads on top at the same origin. ADI design details: centre insert with horizontal seams and a lumbar panel, three vertical stripes on the upper backrest, three stripes on the outer front corner of the cushion following its contour, piping on the outer backrest, cushion and headrest edges, plain stitched seam between insert and bolsters, rear pocket, piped headrest with a flat embroidery area. Deliverables: .blend source, base GLB, design GLB, panel map CSV, six studio renders (both sides, front, rear, front and rear three‑quarter) in black with white piping and stripes. Deadline: [date]. Budget: [amount]. Stage 2: full set (separate milestones) Base seats: front driver, front passenger (proper mirrored geometry with non‑mirrored UVs), rear three‑seat bench with a 60/40 split seam, armrest outline and three headrests. Seven cover designs, each on all three positions: Angel Wings, Ice Silk, Ice Rosa, Original Car Line, ADI, Lingjue Fashion, Lingdu Awakening. Quilting, ridges and seams as geometry; fine stitching, perforation and micro‑quilting in normal maps. Material texture library: tileable, colour‑neutral normal and roughness sets for smooth, nappa and lychee leatherette, suede, ice‑silk fabric, neoprene and canvas, 1024 px, with a stated real‑world tile size. Per design: panel map CSV and labelled PNG, turntable renders (8 stills at 45° plus a close‑up), one colour test render. Final README with versions, texel density and tile sizes. Timeline: [weeks]. Budget: [amount]. Technical requirements Blender 4.2 LTS or newer. Metres at real scale (bucket seat about 0.55 m wide, 1.2 to 1.3 m to the headrest top). GLB: Y‑up, seat facing +Z, origin on the floor centred under the cushion, transforms applied. Naming is critical because code finds parts by name. One mesh per customisable part, lower case with underscores: cover_ (for example cover_backrest_centre, cover_cushion_bolster_left), piping , stripe_ , stitch_ , zone_embroidery_ , hw_ for hardware. Material names are mat_ plus the mesh name. Same names for the same panel across all designs. Left and right are the occupant's. Customisable parts in neutral light grey with standard glTF metallic‑roughness materials only, no extensions. Colour is applied at run time. Stitch lines as thin separate meshes with a small tiling stitch texture and alpha mask, grouped so each group takes one thread colour. Piping and stripes as separate meshes. UV0 non‑overlapping, consistent texel density (state it), upright toward the headrest. Each embroidery zone is a thin conforming mesh with its own undistorted 0 to 1 UV square on every headrest front. UV1 optional for baked ambient occlusion. Budgets: front seat, base plus one cover, under 60,000 triangles and 3 MB. Rear bench under 90,000 triangles and 4 MB. No Draco or Meshopt, no embedded cameras or lights, no unused materials. Every file passes the Khronos glTF Validator with zero errors. Quality bar The seats must read as premium, tailored upholstery, not a smooth shell with lines drawn on it. Deep side bolsters that wrap forward, stuffed panels with real seam valleys, stitching sitting in the seams, piping following the contour, a sculpted plastic base, and no faceting or pinching at close range. Side by side with the reference photos at matching angles, proportions and panel layout must clearly match. I will supply catalogue photos, finished‑product photos, a reference render and material swatches on award.
