Provides real eye tracking and lip tracking in VRChat via the HTC Vive Pro Eye's SRanipal SDK.
For this app to work, you'll need to be using an avatar with the correct parameters or an avatar config file with the correct mappings. The system is designed to control your avatar's eyes and lips via simple blend states but what the parameters control is completely up to you.
Here is a template that you can use to add face/eye tracking to your avatar. You can replace the animations in the template with your own, or simply use this template as a reference. This template includes Oscmooth which is required to have your animations look smooth to other people! To have smooth animations in less parameters space, you can use Binary Parameters.
It's not required to use all of these parameters. Similar to the setup of parameters with Unity Animation Controllers, these are all case-sensitive and must be copied EXACTLY as shown into your Avatar's base parameters. A typical setup might look something like this:
If your avatar uses bones for eye control, you can toss this controller on your additive layer for 1-1 gaze tracking, though you will still need to add blink/squeeze/widen blendshapes on your fx layer.
Please make sure you disable the built in simulated eye tracking in your avatar descriptor. This will almost certainly mess with things if left on. Personally, I've also had some issues with blink blendshapes being overrided by my gesture layer so if you can see your eyes fine but others see them half closed, I would reccomend removing your Additive layer so the default is not applied. It should say "None (Runtime Animator Controller)" if it's removed correctly.
Feel free to consult the wiki for a setup guide and more info as to what each parameter does
There are a large number of parameters you can use for lip tracking.
