It took an entire day of troubleshooting but I finally managed get it to work. Is anyone even using the Droolon F1? There are a number of mistakes and unclear instructions in the SDK. Please fix this otherwise every developer is going to get stuck. Here's what I did:
1) Download and extract Cosmos&VIVE&VIVEPro_SDK&Document(DC) from 7invensun's website
2) Run VIVE_SRanipalInstaller.msi
3) After installation, copy the entire SRanipal folder contents into C:\Program Files\VIVE\SRanipal, overwriting all files. The files from the installer do not support the Droolon and will not work.
4) Start SR_Runtime. In Steam VR's menu start eye calibration
5) After successful calibration, import DroolonF1-Unity-Plugin.unitypackage into Unity
6) Copy the Plugins folder (except openvr_api.dll) from SRanipal_SDK_7/FaceGym/FaceGym_Data/ into your Unity project ViveSR/Plugins overwriting the existing. The ones in the unitypackage are outdated and will not work.
7) Open and run the EyeSample_v2 scene and hopefully everything works!
