Hiiii
I’m working on integrating custom SlimeVR trackers (ESP32 + MPU6050) with Unreal Engine 5 VR using OpenXR.
The trackers are:
Working correctly in SlimeVR Server
Visible and tracked properly in SteamVR
SteamVR is set as the OpenXR runtime
But these trackers are not showing anything in Unreal
In Unreal:
OpenXR and OpenXR Vive Tracker plugins are enabled
Motion Controller / Get Motion Controller Data does not work (expected, since these are body trackers, not hand controllers)
The issue is:
👉 I cannot find the Blueprint node “Get Vive Tracker Pose” (or any Vive/OpenXR tracker pose node) in Actor/Pawn Blueprints, even with Context Sensitive off and after restarting the editor.
I want to confirm:
Is this node renamed or removed in UE 5.4?
Is there a different recommended OpenXR node/API to read SlimeVR / Vive style body trackers in UE5?
Or is this supposed to be accessed only via C++ OpenXR APIs now?
Any guidance on the correct UE5 workflow for reading OpenXR body trackers would really help.
Thanks!
