3D Bike Rider Rigging

# 3D Artist Needed - Cycling Game (WebGL / [login to view URL]) ## Overview We are building a browser-based cycling race simulator (similar to Zwift / TrainerRoad style visuals). We need a 3D artist to create a library of optimized rider and bike assets for real-time WebGL rendering using [login to view URL] / React Three Fiber. The visual style should be: * Stylised-realistic (not photorealistic, not cartoon) * Clean, smooth, readable at distance * Performance-optimised for up to 30 riders on screen --- ## Core Requirements ### File Format * Format: GLB (glTF binary) * Units: Metres, Y-up coordinate system * Textures: Embedded in GLB * Animations: Included as named clips * Compression: Draco preferred --- ## Model Structure Rider and bike must be separate meshes within the same GLB. ### Rider Structure * Body (torso, arms, legs) * Head * Hair (separate mesh) * Jersey (separate mesh) * Shorts (separate mesh) * Shoes * Helmet * Gloves * Sunglasses (optional) ### Bike Structure * Frame * Handlebars * Wheels * Saddle * Cranks * Pedals * Tyres Reason: We need to swap materials (kits, colours, etc.) at runtime. --- ## Polygon Budget * Rider: 4,000 to 8,000 triangles * Bike: 2,000 to 5,000 triangles * Total per rider: 6,000 to 13,000 triangles Target: 30 riders on screen simultaneously --- ## Rider Variations We need 4 base rider models: * Male standard * Male muscular (sprinter) * Female standard * Female lean (climber) All must: * Share the same skeleton/rig * Share the same UV layout --- ## Customisation System These will be applied at runtime: ### Skin tones (via material colour) 6 variations (light to dark) ### Hair * 4 styles: * Short * Medium * Ponytail * Bald * 9 colour options ### Facial Hair (male only) * Stubble * Beard * Moustache --- ## Bike Variants 4 frame styles: * All-rounder * Aero * Lightweight climber * Endurance / gravel All must use identical attachment points. ### Bike customisation * 12 colour options (material-based) * 2 wheel types: * Standard * Deep-section aero --- ## Jersey / Kit System We require 40 jersey textures (1024 x 1024 PNG): * 16 solid colour kits * 20 national kits (flag-inspired designs) * 4 special kits: * World Champion * Polka dot (KOM) * Green (sprint) * Yellow (leader) Important: * All jerseys must share the same UV layout * Provide a UV template file --- ## Animations Required All animations must be included in the GLB. Clips: * pedal_seated (loop) * pedal_standing (loop) * sprint (loop) * coast (static) * aero_tuck (loop) * idle (loop) * look_back (one-shot) * celebrate (one-shot) Requirements: * Work across all 4 rider body types * Smooth transitions between animations * Crank motion included in animation * Wheel rotation handled in code --- ## Rig Requirements Standard humanoid rig: * Hips, spine, chest, neck, head * Arms and legs fully rigged Bike attachment points: * Pedals (left/right) * Hand grips * Saddle * Wheel axes Rider must align correctly with bike: * Feet locked to pedals * Hands on handlebars --- ## Deliverables ### Rider Files * 4 rider GLBs (one per body type, with full animations) ### Hair and Facial Assets * 3 hair meshes * 3 facial hair meshes ### Bike Files * 4 bike GLBs (one per frame style, both wheel types included) ### Textures * 40 jersey textures * Base skin texture * UV templates ### Reference Files * UV layout diagrams * Skeleton reference * Attachment point reference --- ## Technical Requirements * Must work in [login to view URL] / React Three Fiber * Use PBR materials (metallic-roughness) * No baked lighting * Single UV channel * All transforms applied before export * Meshes triangulated Test using: [[login to view URL]]([login to view URL]) --- ## Nice to Have (Not Required) * Experience with game-ready assets * Experience with WebGL optimisation * Experience exporting clean GLB files from Blender --- ## Goal This system will allow us to generate millions of rider combinations through: * Body type * Skin tone * Hair * Kit * Bike setup --- ## To Apply Please include: * Portfolio (game assets or similar) * Example of rigged character work * Example of animation work (if available) * Estimated timeline * Estimated cost --- ## Notes This is the foundation asset system for a larger cycling platform. There is strong potential for ongoing work (additional animations, environments,
