Preset Options
During installation, you will see preset choices such as:
- HD
- HD (VIVE)
- HD (Quest, Pico)
- SD
Available options may change by version, but naming remains consistent.
HDvsSD: Resolution profile (HDis higher fidelity but uses more synced parameters).- Device label in parentheses: Optimized for that device class.
- No device label: General profile using more parameters for broad compatibility.
TIP
If you use multiple devices, select the general (non-device-specific) version.
Parameter Resolution
Face tracking uses many Expression Parameters for network sync, and VRChat limits this to 256 bits.
Booluses1bitIntandFloatuse8bits
The framework uses parameter quantization to reduce the bit cost needed for float-like behavior.
VIVE vs Quest/Pico Differences
VIVE (SRanipal parameters), compared with Quest/Pico:
- Eye tracking: No eyebrow detection, but includes pupil diameter detection.
- Mouth tracking: No
MouthDimple,MouthStretch, orNoseSneer.
INFO
This description specifically applies to VIVE Pro Eye.
These devices do not support pupil diameter and also do not support EyeWide and EyeSquint:
- VIVE Focus 3 + Facial Expression Detection Kit
- VIVE Focus Vision
- VIVE XR Elite + Full-Face Detection Kit
For mouth capture quality, VIVE devices are generally similar.
