Hello,
While using Vive Trackers through the OpenXRViveTracker plugin, we noticed that some tracker roles available in SteamVR do not seem to be exposed as MotionControllerComponent MotionSources in Unreal.
For example, SteamVR allows assigning roles such as:
Left Wrist / Right Wrist
Left Ankle / Right Ankle
…
But those roles are not available in the motion source drop down list in unreal, and we even tried manually writing the string in MotionSource field but it was not recognized.
We also found the SteamVR “Held In Hand” Role (with subsettings Any Hand, Left Hand, Right Hand) works with “Gun” as MotionSource
And “Keyboard” corresponds as “Pad”
After digging a bit in the engine source code, we found in “Engine\Plugins\Runtime\OpenXRViveTracker\Source\OpenXRViveTracker\Private\OpenXRViveTracker.cpp” line 147 a list of strings that seems to match the SteamVR roles currently supported.
Is there a technical reason for this limitation, or is support for the additional SteamVR tracker roles planned in a future engine release?
It would be very helpful if the plugin could expose all roles available through SteamVR/OpenXR so developers can take advantage of the full tracker ecosystem without maintaining custom engine modifications.
Thank you for your help and clarification.
Best regards,
Malek
