No need to install into avatar
This sleep animation system for VR is compatible with VRChat's OSC Trackers.

Overview:

RBS OSC SuiminSystem is a virtual sleep tracker application designed for VR experiences. It is compatible with VRChat's OSC trackers.

With this application, you can seamlessly switch between different sleeping poses such as supine, prone, and sideways, without the need to integrate them into the avatar, which was previously a requirement.

Features:

Seamless switching between poses: You can effortlessly switch between supine, prone, and sideways sleeping positions without the need for the cumbersome FootAnchor toggle.

No need to install into the avatar: Additionally, there is no longer a need to open Unity and install a sleep system into your avatar. Menu assets are included for those who wish to control the FootAnchor and other features, but excluding them will not affect the functionality. It's a bonus feature!
