I need a skilled Unity 3D developer to build a full-featured car-racing game. The core experience must feel fast and authentic, so realistic physics is non-negotiable; I expect tight handling, believable collisions, and visible weight transfer. Competitive play is central to the concept, therefore a smooth, real-time multiplayer mode has to run reliably on desktop and mobile. Tracks should be based on a real-world map I will supply (road layout, elevation data, and reference photos are ready). You can suggest the most efficient workflow—whether that’s importing GIS data, sculpting terrain directly in Unity, or leveraging external tools like Blender—so long as the finished circuit looks and drives like its real counterpart. I plan to use standard Unity pipelines: C#, URP/HDRP where appropriate, and either Photon, Mirror, or Unity Netcode for networking (choose the option you are most comfortable optimising). Feel free to integrate any proven racing-specific assets for vehicle physics, as long as the end result can be customised later. Deliverables • Playable prototype with one fully modelled track, at least two car prefabs, and functional online lobbies • Clean, well-commented Unity project files and C# scripts • Brief setup document explaining scene hierarchy, networking configuration, and how to add new tracks or vehicles The project will be reviewed against frame-rate stability, accuracy of the physics, and seamless multiplayer synchronisation. If everything aligns, we will extend the scope to additional cars, deeper customisation, and matchmaking features.

Hi, Racing games sit at the intersection of physics tuning, netcode, and performance — three areas where I have direct hands-on experience. On the game side I led Mine Quest 2 (published mobile title) and have shipped multiplayer work across Ludo and card games using Photon, so lobby flow, room management, and real-time sync are familiar territory rather than new ground. On the technical side my background in computational geometry and 3D mesh work (including Direct3D/OpenGL prototypes and Unity geometry tooling) means track construction from real-world elevation data is something I can approach practically, not speculatively. Straight talk on the budget range: $10–4,000 covers a wide spread, and the full deliverable list — realistic vehicle physics, real-world track modelling, multiplayer lobbies, two car prefabs, clean architecture docs — is realistically a $3,500–6,000+ engagement at my rate even scoped tightly. A genuinely polished racing feel (weight transfer, suspension, collision response) alone takes significant iteration. That said, a solid prototype is achievable within the upper end of your range if we scope it carefully. For a $3,500–4,000 fixed engagement, here is what I'd deliver: Phase 1 ($3,500–4,000, ~6–7 weeks): Playable prototype — one real-world track, two drivable cars, online lobbies - Real-world track built from your GIS/elevation data via Blender → Unity terrain pipeline, URP-lit - Vehicle physics using a proven asset (NWH Vehicle Physics or similar) tuned for weight transfer and collision response - Photon Fusion lobby system: host/join, race start, real-time position sync, disconnect handling - Two car prefabs with customisable parameters and basic LODs for mobile frame-rate targets - Setup doc: scene hierarchy, networking config, guide for adding tracks and vehicles Phase 2 (quoted separately): additional cars, matchmaking, deeper customisation. Two questions before I finalise scope: Is $4,000 your hard ceiling, or a starting point you can flex if the prototype lands well? And do you have a target player count per lobby — 4, 8, 16+? That determines networking architecture meaningfully. 10+ years full-stack. Preferred Freelancer, 5.0 across 34 reviews, 33 completed projects, 95% on-budget.

Hi, I can develop your realistic multiplayer car racing game in Unity with tight physics and competitive online gameplay. I have already developed similar platforms involving real-time vehicle systems, lobby-based multiplayer, and optimized mobile/desktop builds. Approach: • Physics: custom tuned vehicle controller (WheelCollider/Raycast hybrid) for weight transfer, drift, and collision realism • Track: import GIS/heightmap data + Blender/Unity terrain workflow for accurate real-world replication • Multiplayer: Photon Fusion (low-latency, reliable sync) with lobby/room system • Optimization: URP/HDRP setup with performance profiling for stable FPS on mobile & PC Deliverables include a playable prototype, 1 detailed track, 2 car prefabs, working online lobbies, and clean documented C# project. Questions: What is your target player count per race (8, 12, 20+)? Will you provide GIS data in OSM/heightmap format or should I design the full import pipeline? Looking forward to building this into a scalable racing platform. Thanks Rahul

Hi I can build the Unity 3D car-racing prototype with realistic vehicle physics, one real-world-based track, two car prefabs, and real-time multiplayer lobbies for desktop and mobile. I have experience with Unity, C#, URP/HDRP, vehicle controllers, collision tuning, terrain workflows, Blender/GIS-assisted track creation, Photon, Mirror, Unity Netcode, and mobile performance optimization. A key technical problem is keeping realistic driving physics and multiplayer synchronization stable across devices without frame drops, jitter, or inaccurate car movement. I would solve this by using a proven vehicle physics base, tuning suspension, tire grip, weight transfer, collision response, and syncing only the required network states with prediction/interpolation. For the real-world track, I can build the road layout, elevation, terrain, barriers, checkpoints, and environment using your map data and reference photos. I can also structure the Unity project cleanly with documented scenes, prefabs, scripts, networking setup, and clear instructions for adding more cars or tracks later. My focus is to deliver a fast, authentic, and maintainable racing prototype that can grow into a larger multiplayer game. Thanks, Hercules

The part I would focus on first is the actual driving feel, not menus or decoration. If the car does not handle well, collide believably, and stay smooth online, the rest of the racing game will not matter. I would begin by building one testable Unity prototype: import your supplied road layout/elevation references, block out the real track, place two car prefabs, tune suspension/grip/braking/weight transfer, then test laps until the handling feels fast but controllable. After that, I would add barriers, terrain cleanup, visual details, checkpoints, lap timing, and a basic lobby so two or more players can race online. For multiplayer, I would keep the first version practical: synchronize position, rotation, speed, lap state, collisions, and race start/finish cleanly before adding advanced matchmaking. I can work with Photon, Mirror, or Unity Netcode, depending on what you prefer for hosting and future scaling. I have worked with Unity/C#, vehicle physics, multiplayer prototypes, scene optimization, asset setup, and clean project handoff. I would keep the project organized so new tracks and vehicles can be added later without rebuilding the base system. Do you already have the real-world track data as elevation/GIS files, or should I build it from road images and reference photos? Thank you Mykola Sagin
