For the time being, my main goal is to map 3 random trackers, a waist and 2 feet to their respective steam vr positions to that they will be recognized by the addon, allowing me to finally see the "Calibrate Fullbody trackin" option in the settings, like this https://cdn.discordapp.com/attachments/382173212810936320/761142294598385684/fbt_instructions.png (if you cant open the link just post it on discord and it will open the image automatically)

Using pico connect does not work, the addon does not seem recognize pico motion trackers through it even if ive already assigned a body part to each tracker through steam vr (The waist is a virtual tracker, however since it is recognized by steam vr it shouldn't be an issue)

Alright i managed to make the "calibrate full body tracking" option appear with the most scuffed slime vr setup imaginable (2 joycons for my feet using the slime vr wrangler and my phone for the waist using owotrack) this probably works because slimvr shows its trackers as vive trackers in steam vr which leads me to think the "emulate vive trackers" option on virtual desktop might actually allow the pico trackers to work as they would be disguised as vive trackers

Got it to work, you need to use the virtual desktop app on pico and select the "emulate vive tracker" option, from then on the addon should recognize both your physical pico trackers as well as the virtual ones
