>>19898736Alright, I'll break this down because I've seen a lot of confusion about how they're doing the tracking, if they're in the same room, why it's scuffed. etc.
They're all in their own homes wearing SteamVR compatible headsets (Vive or Index) that utilize what are called SteamVR Base Stations (or lighthouses) to track the headset, controllers, and any other compatible accessories or peripherals. The Base Stations work through IR light pulses and lasers to identify and track sensors on objects, as seen in the .gif.
Because these base stations only track in a wide area in front of them, this means that two are generally in use at the same time to prevent tracked objects from being covered (from turning around, objects in the tracked space, etc.) and placed in opposite corners of the room.
The placement effects tracking A LOT, and body trackers/controllers/headsets will freak out immediately if they aren't being detected. And because it relies on light and laser pulses to track, any reflective surface (like glass or mirrors) will confuse the tracking and cause it to bug out. This means if you want optimal tracking, you'll have to change your room to accommodate VR, which is why many hardcore users have dedicated VR rooms free of any other objects and any windows covered.
Combine these problems with how VRChat has some real shitty inverse-kinematics that they're only now working on improving, and you're in scuff city.
My guess is that Gura and Ame have rooms more suited to VR, having clear space and no reflective surfaces, and Kiara having possible mirrors or unoptimal base station coverage due to limited space. If she fixes a few things she'll be perfectly fine (except ditch the Vive for an Index, or at least buy a ModMic. plz chimgm.)
>t. hardcore VR and body tracking autist
