PitLane Director AC is a broadcast director tool for Assetto Corsa. It gives you a complete race production dashboard — live leaderboard, AI-powered camera direction, professional broadcast overlays, and OBS integration — all from a single application running alongside AC on your broadcast PC.
What's included
- Live race dashboard with leaderboard, battle detection, minimap, and program monitor
- AI Director that automatically picks the best camera angles based on race action
- 10 broadcast overlays (5 Advanced Broadcast overlays + 5 customizable templates) served to OBS as browser sources

- Camera controls with keyboard shortcuts and a visual toolbar
- Events feed that detects overtakes, battles, incidents, pit stops, and fastest laps in real time

| Assetto Corsa | Installed with Content Manager |
| Custom Shaders Patch | Any recent version with Lua app support |

How it works
PitLane runs as a separate application alongside Assetto Corsa on the same PC. It reads race data through two channels:
- CSP Lua sidecar — a small script that runs inside AC via Custom Shaders Patch, sending all car data to PitLane over a local network connection at 10 times per second. This is deployed automatically when you set your AC install path in PitLane.
- AC SharedMemory — Windows shared memory that provides deep telemetry for the currently spectated car.
You don't need to install anything on other players' machines. PitLane works entirely from the broadcaster's PC — no driver buy-in required.
Overlays are served as web pages on localhost:9100 and displayed in your stream via OBS browser sources.
