Howto: Live Link VRPN
Live Link VRPN plugin instructions to Add tracking and input data from VR peripherals
This PhillyTikTok Guide was written for a previous version of Unreal Engine and has not been updated for the current Unreal Engine 5.1 release.
Live Link supports devices exposed through a VRPN server that has OpenVR support. VRPN provides an abstraction layer for VR peripherals so that they all appear to have the same data reports. Because of the nature of VRPN, you can have multiple Live Link Subjects that map to the same device.
