# Third-Person Starter V0 Template: Deploy-First Guide for React Three Fiber - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Third-Person Starter v0 template gives you a working browser 3D character controller built with React Three Fiber, @react-three/drei, and Three.js. You get WASD movement, an orbit camera that follows the player, HDRI lighting, and a 2D HUD overlay — all in Next.js. Deploy to Vercel immediately; V0 preview won't run 3D correctly. The prompt pack covers GLTF character models, running animations, jump mechanics, multi-scene portals, and a Supabase shared world. ## Frequently asked questions ### Is this template free to fork and use? Yes. Forking v0.dev community templates is free with a v0.dev account. The fork consumes no credits. Deploying to Vercel is free on the Hobby plan. The libraries used — @react-three/fiber, @react-three/drei, Three.js, and Next.js — are all open-source (MIT licensed). ### Can I use this template commercially? Yes. You own the code output of your V0 fork and can use it in commercial products and client projects. Three.js, react-three-fiber, and all drei helpers are MIT licensed and permit commercial use without attribution requirements. ### Why does my fork break in V0 preview — I see a blank canvas or loading spinner that never resolves? This is expected behavior for 3D templates. V0's esm.sh preview sandbox cannot reliably load @react-three/fiber and Three.js because these libraries are too large for the browser-based sandboxed environment. The correct workflow for this template is: fork → publish immediately (Share → Publish → Publish to Production) → test only on the live Vercel URL. Do not attempt to debug 3D rendering in V0 preview. ### What browsers support this template? Desktop Chrome and Firefox provide the best WebGL 2 performance and full pointer lock support. Safari works but may show reduced frame rates on some hardware configurations. Mobile browsers are not recommended for the base template because pointer lock (used for camera control) doesn't work on touch devices — you'd need to add a custom virtual joystick to HUDOverlay. ### How do I add my own 3D character model? Place your .glb file at /public/models/character.glb and use the first prompt from the prompt pack above. It loads the model with useGLTF from @react-three/drei, wraps it in Suspense, and connects it to the existing MovementController. Free rigged GLTF characters with animations are available from Mixamo at mixamo.com. ### How do I connect a database or add multiplayer? Use the Supabase shared world prompt from the prompt pack above. It sets up a player_positions table with Supabase Realtime subscriptions so players can see each other move. Add NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY to the V0 Vars panel before publishing. Test the multiplayer feature on the Vercel URL, not in V0 preview. ### Can RapidDev help me build a full 3D experience with this template as a starting point? Yes. RapidDev extends V0 3D starters into full interactive experiences — adding asset pipelines, physics via Rapier, performance optimization, and production deployment. Visit rapidevelopers.com to discuss your 3D project. ### Does this template support physics for collisions and jumping? The base template has a minimal collision system for staying on the ground plane. For full physics (jumping, rigidbody collisions, character controller), install @react-three/rapier and use the jump prompt from the pack for gravity-based jumping. The Rapier gotcha in this page covers the common 'falls through ground' issue you'll hit when adding Rapier. --- Source: https://www.rapidevelopers.com/v0-template/third-person-starter © RapidDev — https://www.rapidevelopers.com/v0-template/third-person-starter
