VSP MobiLab Posted January 31, 2023 Share Posted January 31, 2023 I had the same issues. Either Unity was crashing or the DLL was not found. Here is my solution: Tested with Unity 2022.2.3f1 / Unity 2020.3.44f1, VIVE OpenXR Plugin - Windows 1.0.10, SRanipal Runtime 1.3.5.5 and SRanipal SDK 1.3.3.0 The current SRanipal Runtime (1.3.5.5) should already be installed on your PC after completing the PC VR HEADSET SETUP https://www.vive.com/us/setup/pc-vr/ @Kate.kate said you need version 1.3.2.0 to extract eye tracking data. This is not true for me, but you can find the older version here: https://hub.vive.com/en-US/download/ The current SRanipal SDK (1.3.6.8) makes Unity crash. Get version 1.3.3.0 from the archive: https://developer.vive.com/resources/vive-sense/eye-and-facial-tracking-sdk/download/archive/1_3_3_0/ If not done yet, install the XR Plugin Management via Edit > Project Settings > XR Plugin Management. Add the Vive Package Repository for the Package Manager: Edit > Project Settings > Package Manager > Scoped Registries Name: VIVE URL: https://npm-registry.vive.com Scope(s): com.htc.upm Open Package Manager, select My Registries in top row and install VIVE OpenXR Plugin - Windows. A pop-up appears and requests the restart of the editor to enable the new input system. Click Yes and wait for the restart to be completed. Open XR Plugin Management via Edit > Project Settings > XR Plugin Management. Activate OpenXR and Vive OpenXR feature group. Import SRanipal SDK: Assets > Import Package > Custom Package... Open OpenXR settings via Edit > Project Settings > XR Plugin Management > OpenXR Unselect Facial Tracking, Hand Tracking and Scene Understanding. Close and re-open Unity! Without the restart, the DLL won't be found. (Took me hours to figure this out.) Test if everything works by dragging the SRanipal Eye Framework prefab in your Scene and running the scene. I followed this tutorial for extracting the eye data and adapted the script to my needs, works perfectly: https://forum.htc.com/topic/9341-vive-eye-tracking-at-120hz/ Link to comment Share on other sites More sharing options...
AirMouse Posted June 20 Share Posted June 20 Just updated to SRanipal Runtime (1.3.6.12) and is very unstable, the runtime keeps crashing, and sometimes my project crashes. Now I get status messages like: Lip Camera Version "Checking" , then after 30 seconds it says "updated the lip tracker firmware", then i am instructed to reboot the HMD, even when SteamVR is not running, this is a repeating, and now nothing works. Way my lip tracker camera just ruined by a update? I think the SR face capture is really awful to work with, it's so unstable and I have a modern PC, lots of my friends (i am a animator) agree the Vive face trackers works only about 15% of the time. It's a mess, and was really the only reason I purchased a Vive pro eye, now I can't even use the damn thing because the software is begin destroyed by a team of reckless "software developers" who literally have HTC funding to do a simple college level project implementation and can't even get that right, and ends up costing consumers $1000 to only realize the hardware is so broken I have to spend literally two hours trying to get the stupid face tracking working on a "PRO" level product is absurd, what a rip off. HTC could have done way better on face tracking support, but SRanipal just proves they don't give a ... about VR Link to comment Share on other sites More sharing options...
