Pimax Crystal

note

This guide assumes you have PimaxPlay installed alongside SteamVR. If you do not have PimaxPlay installed, please install it before continuing.

Summary​

Unlike other Pimax HMD's, the Pimax Crystal requires a different setup. This guide will show you how to set up your Pimax Crystal for VRCFaceTracking.

Requirements​

Set-up​

Installation​

Create a folder on your desktop to store all of the files you will be downloading. This will make it easier to find them later.

1) Install and configure PimaxPlay​

First, open PimaxPlay and go to the settings tab. Ensure that the eye tracking option is enabled in the device settings, and perform an eye-tracking calibration.

2) Install BrokenEye​

Download the latest release and extract BrokenEye.exe into the folder you created.

note

While SRanipal v1.3.1.1 does work with BrokenEye, we strongly recommend using v1.3.6.5 as it has been shown to have more consistent and reliable eyelid tracking over v1.3.1.1 when used with the Crystal.

Download SRanipal_1.3.6.5.zip from the VRCFaceTracking Discord Server in #file-share and extract the contents into the same folder as BrokenEye.exe. You do NOT need to run SRanipal.

danger

Ensure that the contents are NOT in a sub-folder and are in the same directory as BrokenEye.exe

note

Only the following files are necessary.

  • EyePredictionModule.dll
  • EyePredictionTVM.dll
  • OpenCL.dll
  • opencv_world310.dll
  • tvm_runtime.dll
  • model\EyePrediction\00-0000.params_opencl.dll
  • model\EyePrediction\00-0000.params_opencl.json
  • model\EyePrediction\00-0000.params_opencl.params

Unnecessary files can be safely deleted.

4) Install the VRCFT-Tobii-Advanced Module​

Launch VRCFaceTracking, and from the Modules tab, click the "Install from package" button at the top, and select the VRCFT-Tobii-Advanced Module. Upon relaunch of the application, you should see a new module called "Tobii Advanced" being loaded.

5) All together now!​

Now that you have all of the required software installed, it's time to put it all together. First, launch PimaxPlay and SteamVR. Once SteamVR is running, launch BrokenEye.exe. If the eye tracker is not automatically connected, click "Connect to device" Then, launch VRCFaceTracking. Done!

Uninstalling The VRCFT-Tobii-Advanced Module​

To uninstall The VRCFT-Tobii-Advanced Module, go to the Module Registry, select the VRCFT-Tobii-Advanced Module and click the uninstall button at the bottom.
