archportal tracker

ArchPortal Tracker turns an iPhone or iPad into a camera tracking source for Unreal Engine.

It streams ARKit position and rotation data over UDP to a LONET 2 Live Link source, registering as the subject ArchPortal_Rig on port 60608. Point it at your workstation's IP address, mount the device to your camera, and drive a CineCameraActor in real time.

Built for virtual production work and released free.

WHAT IT DOES
Streams ARKit world tracking position and rotation to Unreal Engine
LONET 2 Live Link protocol over UDP, port 60608
Live telemetry readout — position in centimetres, rotation as a quaternion
Socket status indicator so you can see the connection state
Reset origin to set world zero from your current position
Framing reticle for lining up before you reset
Works over Wi-Fi or a wired USB Ethernet adapter

WHAT YOU NEED
A device that supports ARKit
Unreal Engine with the LONET 2 plugin
Both on the same local network, or connected directly by Ethernet

The app sends transform data only. Focal length, aperture and frame rate are set on the CineCameraActor in Unreal.

MOUNTING

Mount the device right-side horizontal. The mount orientation is built into the coordinate transform and cannot be changed in the app.

PRIVACY

No account. No analytics. No advertising. No data collection of any kind. Camera access is used only by ARKit to determine device position — no image data is recorded, stored, or transmitted. The only network traffic is the tracking data you send to an address you type in yourself.
