Rite Media LiveLink Plugin Setup — IP/Port Configuration, Step-by-Step¶

Summary¶

The Rite Media LiveLink plugin (GitHub: KevinRiTE/RiTE_MRMC_LiveLink) connects Flair's 50Hz XYZ tracking output to Unreal Engine via the LiveLink protocol. The plugin listens on port 55535 by default. Setup requires: enabling 50Hz XYZ output in Flair, installing and enabling the plugin in Unreal, adding an MRMC LiveLink Source pointed at the Flair PC's IP address and port 55535, and applying the resulting LiveLink subject to a CineCamera Actor. The data includes all six degrees of freedom (X, Y, Z, pan, tilt, roll) plus focus and zoom if configured. On UE5 the setup takes approximately 10 minutes from a fresh install.

[RESOLVED] Full Setup Procedure¶

Community — Rite Media plugin documentation + forum

In Flair: 1. Go to Output → 50Hz XYZ (or FreeD, depending on plugin version). 2. Set the destination IP address to the Unreal PC's IP address. 3. Set the port to 55535 (default; must match the plugin's listening port). 4. Enable the output. 5. Confirm data is being sent (check the output status indicator in Flair).

In Unreal Engine: 1. In the Plugins browser, find and enable the Rite Media MRMC LiveLink plugin. 2. Restart the Unreal Editor. 3. Open Window → Live Link. 4. Click + Source → select MRMC LiveLink Source (or similar, depending on plugin version). 5. Enter the Flair PC's IP address and port 55535. 6. Click Create. The LiveLink panel should show a connected source with incoming data. 7. In your scene, add or select a CineCamera Actor. 8. Add a LiveLink Controller component to the CineCamera. 9. Set the LiveLink Subject to the MRMC source. 10. Press Play — the CineCamera should track the robot's live position.

[RESOLVED] Port 55535 — Default and Most Common¶

Community

The default plugin port is 55535. If the connection doesn't work, verify both Flair's output port and the plugin's listening port are set to the same value. Also check that Windows Firewall on the Unreal PC is not blocking UDP port 55535 inbound.

[RESOLVED] UE4.27 Requires C++ Project for Plugin Compilation¶

Community — see also VP-rite-media-plugin-ue427-recompile.md

In UE4.27, the plugin cannot be installed into a Blueprints-only project because it contains C++ code that must be compiled. Convert the project to a C++ project first (File → Convert to C++) before adding the plugin.

[RESOLVED] "Receiving Data" Shown but No Camera Movement — Common Causes¶

Community

If the LiveLink panel shows "Connected" and "Receiving data" but the CineCamera does not move, check:

The LiveLink Controller component is added to the correct actor.
The LiveLink Subject Name in the controller matches exactly the source name shown in the LiveLink panel.
The CineCamera is not locked or constrained by another system.
Flair is actively running a move or in live output mode (not paused).
The Flair output IP matches the Unreal PC's actual IP (not 127.0.0.1 unless same PC).
Try rebooting both Flair and the Unreal Editor.
